Configuration of 

CAS Protocols 

This chapter provides instructions for configuring all the channelassociated 

signaling (CAS) protocols in the SP201-SA. Use the sections 

applicable to your SP201-SA’s setup. Before configuring the protocols 

for your SP201-SA, be sure you have completed all the system configuration 

procedures, as described in Section 2.3, System Configuration. 

This chapter contains the following information: 

• Section 3.1, Channel-Associated Signaling in the SP201-SA, provides a brief 

summary of CAS as implemented in the SP201-SA. 

• Section 3.2, Commands for Configuring Channel-Associated Signaling 

Protocols, lists the commands for configuring the protocols discussed in 

this chapter. 

• Section 3.3, Configuring Channel-Associated Signaling Protocols, provides 

procedures for configuring the CAS protocols in the SP201-SA.

configure. 

3.1 Channel-Associated Signaling in the SP201-SA 

Channel-associated signaling (CAS), also known as in-band signaling, 

includes the DTMF, R1, and R2 signaling protocols. R2 has many variants for 

countries and regions. The CAS protocols implemented in the SP201-SA 

conform to the following standards: 

• DTMF conforms to BellCore TR-TSV-002275, Subsection 6.13. 

• R1 conforms to ITU-T Recommendations Q.310–Q.311. 

• R2 conforms to ITU-T Recommendations Q.400–Q.490. (Variants of R2 

also conform to applicable national and local recommendations.) 

• N5 conforms to ITU-T Recommendations Q.140–Q.164. The interworking 

implementation conforms to Q.601–Q.696 Annex B (03/93). 

3.2 Commands for Configuring Channel-Associated 

Signaling Protocols 

Table 3-1 lists the commands used to configure the CAS protocols. 

Note: For commands to configure the common parameters in the SP201-SA 

or for commands to configure other protocols, see the following: 

• Section 2.3, System Configuration 

• Section 4.2, Command for Configuring ISDN Protocols 

• Section 5.1, Non-System-Level Commands Used by More Than One Protocol 

• Section 6.1, Commands for Mapping Timeslots and CICs 

CAS trunks are on the two-port SP201-SA’s port 1 and on the four-port 

SP201-SA’s ports 1 and 2. To verify the ports for CAS trunks, use the 

show trunks command, described in Section 7.2.4.19, The show trunks 

Command.

• Section 5.2.1, The config sp200 Command 

3.3.2 Configuring the DTMF Protocol 

The DTMF protocol implemented in the SP201-SA conforms to BellCore 

Standard TR-TSV-002275, Subsection 6.13. The following sections explain 

how to configure the DTMF protocol in the SP201-SA: 

•Use the config dt command to configure DTMF channels (DS0s). See 

Section 3.3.2.1, The config dt Command. 

• The following task is optional: 

- You can set the conditions that determine when circuit reset (RESCIR) 

messages are sent. See Section 5.2.1, The config sp200 Command. 

3.3.2.1 The config dt Command 

You use the config dt command to configure DTMF channels (DS0s) on the 

SP201-SA. (You configure CAS channels when you place them into service.) 

You can configure one channel at a time, a range of channels on the 

SP201-SA, or all DTMF channels on the SP201-SA at once. 

! 

Caution: Changes you make using the config dt command take effect 

immediately. Changing configuration while calls are in progress may 

result in lost calls or corrupted data. 

Figure 3-1a and Figure 3-1b illustrate the config dt command task flow. 



Note: The first part of the flowchart takes all DTMF channels out of service. 

Then you place selected channels (or all channels) back into service and 

configure them for your network. 

The procedure below shows how to use the command. 

Figure 3-1a. Task Flow for the config dt Command (Part 1) 



Figure 3-1b. Task Flow for the config dt Command (Part 2) 



How to Use the config dt Command 

1 Take all channels out of service by typing config dt all and 

pressing Enter. 

The following prompt is displayed: 

Set 1/1 thru 2/31 out-of-service? (y or n) : 

2 Type y and press Enter. 

The user> prompt is displayed. 

3 Do one of the following: 

a 

To configure a single channel into service, type config dt m:n 

and press Enter. 

where m:n is the trunk:channel you want to put into service. 

A prompt similar to the following is displayed: 

Set m/n out-of-service? : 

Note: You can also use this single-channel option to view the 

configuration for a particular channel, by just pressing Enter to 

accept the current settings. 



b 

To configure several channels into service, type the following and 

press Enter: 

config dt m:n p:q 

where m:n is the beginning of the range of trunks:channels you want 

to put in service, and p:q is the end of the range. (For example, 

config dt 1:1 2:19) 


Set m/n thru p/q out-of-service? : 

c 

To configure all channels in or out of service, type config dt all 




4 Type n and press Enter. 

The specified channel(s) are now in service. A prompt similar to 

the following is displayed: 

Template # for default IAM ? : (range 1 - 5) : 

5 Enter the number of the template you want to use for IAMs sent for 

Signaling System 7 (SS7) calls on the specified channel (the default 

is 1). 




Template # for default ACM ? : (range 1 - 5) : 

6 Enter the number of the template you want to use for ACMs sent for 

SS7 calls on the specified channel (the default is 1). 


DTMF Caller ID/ANI used? (y or n) : 


a 

If you do not want to use Caller ID digits for the specified channel, 

type n (the default) and press Enter. 

The following prompt is displayed. Go to Step 10. 

Provide Wink Start for DTMF originated calls (y or n) : 

 

b 

To use Caller ID digits for the specified channel, type y and press 

Enter. 

Note: When this option is enabled, the SP201-SA collects and 

reports calling party number information, and expects to receive or 

send a calling party number prior to the DTMF called party 

receiving it. 

A prompt similar to the following is displayed. 



Honor C7 Calling Party presentation restriction? (y or n) : 

 

8 If, in Step 7, Caller ID was selected (applicable only for calls from the 

SS7 side to the DTMF side), do one of the following: 

a 

If you want to honor calling party presentation restriction, type y 


Note: If the presentation is restricted, honoring this will remove 

the caller ID. 

b 

If you do not want to honor calling party presentation restriction, 

type n (the default) and press Enter. 

In either case, the following prompt is displayed: 

A-Party comes before B-Party Number? (y or n) : 

9 If, in Step 7, Caller ID was selected, do one of the following: 

a 

b 

If A-party numbers come before B-party numbers, type y and press 

Enter.

n 


a 

b 

To generate a ringback tone for calls that originate from the DTMF 

switch, type y and press Enter. 

To refrain from generating a ringback tone, type n and press Enter. 

In either case, the user> prompt is displayed. 

14 Repeat Step 5 through Step 13 for all groups of channels you are 

putting into service. 

3.3.3 Configuring the R1 Protocol 

The R1 protocol implemented in the SP201-SA conforms to ITU 

Recommendations Q.310 to Q.331 for digital systems using PCM line 

signaling. In addition, the SP201-SA supports BellCore Feature Group D as 

an option on each channel. 

The following sections discuss configuration of the R1 protocol in the 

SP201-SA: 

•Use the config r1 command to configure R1 channels (DS0s). See 


• The following tasks are optional: 



- You can set up entries in the Feature Group D (FGD) information digit 

translation table. See Section 3.3.3.2, The config fgd Command. 

3.3.3.1 The config r1 Command 

You use the config r1 command to configure R1 channels (DS0s) on the 

SP201-SA. (You configure CAS channels when you place them into service.) 



You can configure one channel at a time, several channels at a time (on one 

or more trunks), or all trunks on the SP201-SA at once. 

Figure 3-2a, Figure 3-2b, and Figure 3-2c illustrate the config r1 command 

task flow. 

Note: The first part of the flowchart takes all R1 channels out of service. 



The procedure below explains use of the command. 



Figure 3-2a. Task Flow for the config r1 Command (Part 1) 



Figure 3-2b. Task Flow for the config r1 Command (Part 2) 



Figure 3-2c. Task Flow for the config r1 Command (Part 3) 

How to Use the config r1 Command 

1 Take all channels out of service by doing all of the following: 



a 

At the user> prompt, type config r1 all and press Enter. 


The protocol for link 1 is R1 


b 

Type y and press Enter. 


Note: When a channel is out of service, the R1 line signals are set to 

idle and no messages are sent to the Signaling System 7 (SS7) side. 

The SP201-SA ignores all messages from the SS7 side and all line 

signals from the R1 side. 

2 To configure channels as you put them back into service, do one of 

the following: 

a 

To configure a single channel into service, type config r1 m:n 

and press Enter, 

where m is the trunk and n is the channel (on trunk m) that you want 

to put into service. 


The protocol for link m is R1 





current settings for a particular channel. When the message above 

appears, accept the default of no; then scroll through the options 

that appear (described in Step 4 and subsequent steps). 

If a parameter’s current setting matches the network plan for that 

channel, accept the setting. 

b 

To configure a range of channels into service, type 

config r1 m:n p:q and press Enter, 

where m:n is the beginning of the range (trunk m, channel n) you 

want to put into service, and p:q is the end of the range. (For example, 

config r2 1:1 2:19). 




c 

To configure all channels on the SP201-SA into service, type 

config r1 all and press Enter. 



Set 1/1 thru 2/31 out-of-service? : 


The specified channels are now in service. A prompt similar to 




Template # for default IAM ? : (range 1 - 5) : 

4 Type the number of the template you want to use for IAMs sent out 

on the SS7 side for calls on the selected channels, and press Enter. 

Note: The IAM templates supply line signals required by the SS7 

protocols but not supplied by the CAS protocols. 

The system displays the following prompt: 

Template # for default ACM ? : (range 1 - 5) : 

5 Type the number of the template you want to use for ACMs sent out 

on the SS7 side for calls on this circuit, and press Enter. 

Note: The ACM templates supply message parameters required by 

the SS7 protocols but not provided by the CAS protocols. 


Include Feature Group D (caller ID/ANI)? (y or n) : 


a 

Type n and press Enter if you do not want to use the Feature 

Group D option. 

If you answer no, the system displays the following prompt. Go 

to Step 13. 



Require wink at end of selection? (y or n) : 

b 

Type y and press Enter to turn on the Feature Group D option. 

If this option is turned on, the SP201-SA expects to receive or 

send a calling party number on the R1 side. If you answer yes, the 

system displays the following prompt: 

Use 911-Operator Services Signaling (y or n) : 

7 Answer y (to use a subset of Operator Services Signaling) or n (to use 

the default Exchange Access North American Signaling), and press 

Enter. 


Max nbr of ANI digits to send R1 (0 = all) ? : (range 0 - 32) : 

 

8 Indicate the maximum number of ANI digits to send to the R1 side 

(0 means to send all digits) and press Enter. 

Note: If you set this to zero (the default), each ANI is passed 

exactly as received, regardless of number of digits. If you set this to 

another number, any ANI whose length is less than or equal to the 

number of digits you indicate is passed exactly as received (shorter 

lengths are not padded). Digits are removed from the front of a 

longer ANI until it matches the length indicated. 

The following prompt is displayed; 



Are Information digits supported? (y or n) : 


a 

Type n and press Enter if information digits are not supported. In 

this case, the SP201-SA expects all Feature Group D (FGD) digits to 

be part of the calling party number. 

If you answer no, the system displays the following prompt. Go 

to Step 12. 

Separate Wink required for B-Party Number? (y or n) : 

b 

Type y and press Enter to remove the information digits from the 

ANI (calling party number) sent to the SS7 side on R1-to-SS7 calls 

and to insert the default or translated information digits (for an 

ordinary subscribe) on SS7-to-R1 calls. (In Step 11, you indicate 

whether to use default or translated information digits.) 

If you answer y to the above prompt, the system displays the 

following prompt. 

How many Information digits are to be used? : (range 1 - 2) : 

 

10 Enter the number of information digits to require (1 or the default 2), 


The following prompt appears. 

Use table for translation of Information digits? (y or n) : 

 




a 

Type y and press Enter to use the translation table to translate the 

ANI information digits in the R1 to and from calling party category 

in the IAM on the SS7 side. 

If you type y, the system checks the translation table for a 

matching entry. If none is found, the system uses the default. 

Note: If you answer y to this prompt, you must use the config fgd 

command to configure the translation table. See Section 3.3.3.2, The 

config fgd Command. 

b 

Type n and press Enter to use the default values for the information 

digits. 

The system displays one of the following prompts, according to 

your answer in Step 7: 

• If you indicated y, to use a subset of Operator Services Signaling, 

the following prompt appears. Go to Step 14. 

Generate ringback tone for R1 originated calls? (y or n) : 

 

• If you indicated n, to use Exchange Access North American 

Signaling, the following prompt appears. 

Separate Wink required for B-Party Number? (y or n) : 


a 

Type y and press Enter to require a wink between the calling and 

called party numbers (in addition to the wink before any digits are 

sent). 



b 

Type n and press Enter if you do not want a wink between the calling 

and called party numbers. In this case, there is a wink only before 

any digits are sent. 


Require wink at end of selection? (y or n) : 


a 

Type n and press Enter. 

The system will not send or require an end-of-selection wink 

signal. 

Note: Ordinarily, R1 does not require an acknowledgment wink at 

the end of all of the address signals (also known as selection digits). 

Answer y only if you want the system to send or require this wink 

signal. 

b 


The system requires an end-of-selection wink signal. 

In both cases (y or n), the following prompt is displayed. 


 




a 

b 

Answer y and press Enter to have the SP201-SA generate a ringback 

to the R1 caller. This lets the caller know the call is going through. 

This may be desirable in certain situations—for example, if the 

SP201-SA is connected to a private branch exchange (PBX) that does 

not generate its own ringback tone. This is normally an end-office 

function. 

Answer n and press Enter to pass through end-office ringback to the 

R1 caller while waiting for the call to be answered. 

The user> prompt is displayed. You have now completed 

configuration for the R1 trunks and timeslots you selected. 

15 Perform Step 2 through Step 14 for any additional groups of 

channels you wish to configure for the R1 protocol. 

3.3.3.2 The config fgd Command 

The config fgd command configures the information digits translation table. 

You need to use this command only if, when you used the config r1 

command, you configured channels to use the Feature Group D (FGD) 

information digit translation table. 

Note: To view the table, see Section 7.2.4.11, The show fgd Command. 

How to Use the config fgd Command 

Note: To configure channels to use Feature Group D, see 


1 To add an entry to the information digits translation table, type 

config fgd dd n at the user> prompt, and press Enter. 

In this command, dd represents the information digits (00–99) the 

system will recognize on R1-originated calls, and n is the 

corresponding calling party category (1–15) sent (in the IAM) to an 

SS7 protocol. 



Note: In Step 10 of How to Use the config r1 Command, you indicated 

the number of information digits to require (i.e., the number of 

digits to read). However, you must type two information digits (dd) 

for entries in the table, even if you indicated to require only one 

information digit. 

Enter single digits with a leading zero—for example, 01, 02, etc. 

The entry is added to the bottom of the table. 

Note: When calls originate from the R1 side, the system searches 

the table from top to bottom for a match on the information digits 

(dd). The table finds the first match and sends the corresponding 

calling party category (as part of the IAM) to the SS7 side. 

When calls originate from the SS7 side, the system searches this 

table from top to bottom for a match on the category number (n). It 

uses the first match, and sends the corresponding decimal 

information digits to the R1 in the ANI string. (If there is no match, 

the default information digits are used.) 

! 

Caution: Plan all the logic for this table before you enter any 

data. The table maintains the order in which you enter the 

data. The table may contain several entries with the same 

information digits or calling party category. (Unless you have 

a good reason to maintain multiple entries, we recommend 

that you delete all multiple entries but one.) 

2 If you wish to add another entry to the table, perform Step 1 again. 

3 To delete decimal information digits from the table, type 

config fgd delete dd at the user> prompt and press Enter, 

where dd represents the decimal information digits (00–99) that you 

wish to delete from the table. 

The table deletes the first entry that matches the command. 



Note: When you delete an entry, the table maintains the entry’s 

position as open. The next time you add an entry to the table, it will 

be assigned to the open position. 

3.3.4 Configuring the R2 Protocol 

This section discusses the commands for configuring parameters for R2 

signaling in the SP201-SA. 

The R2 protocol implemented in the SP201-SA conforms to ITU 


signaling. 

The following are the basic steps for configuring R2 channels: 

•Use the config r2 command to configure R2 channels (DS0s). See 


• The following task is optional: 



3.3.4.1 The config r2 Command 

You use the config r2 command to configure R2 channels (DS0s) on the 

SP201-SA into or out of service. You can configure one channel at a time, 

several channels at a time (on one or more trunks), or all trunks on the 

SP201-SA at once. 

Figure 3-3a, Figure 3-3b, Figure 3-3c, and Figure 3-3d illustrate the config r2 

command task flow.

SP201-SA will use has been placed into service. 

3.3.5 Configuring the N5 Protocol 

This section discusses the commands for configuring parameters for N5 

signaling in the SignalPath. 

The N5 protocol implemented in the SignalPath conforms to ITU 


signaling. The interworking implementation conforms to Q.601–Q.696 

Annex B (03/93). 

The following are the basic steps for configuring N5 channels: 

•Use the config n5 command to configure N5 channels (DS0s). See 

Section 3.3.5.1, The config n5 command. 



• The following is optional: 



3.3.5.1 The config n5 command 

You use the config n5 command to configure N5 channels (DS0s) on the 

SP201-SA. You can configure one channel at a time, several channels at a 

time (on one or more trunks), or all trunks at once. The procedure below 

explains use of the command. 

Note: The first part of the procedure takes all N5 channels out of service. 



! 

Caution: Changes you make using the config n5 command take effect 



How to Use the config n5 Command 


a 

Type config n5 all and press Enter. 


The protocol for link 1 is N5 


b 


The user> prompt appears. 




a 

To configure a single channel into service, type config n5 m:n 

and press Enter, where m is the trunk and n is the channel (on 

trunk m) that you want to put into service. 


The protocol for link m is N5 








b 


config n5 m:n p:q and press Enter, 



config n5 1:1 3:24). 


The protocol for link m is N5 


c 

To configure all channels into service, type config n5 all and 

press Enter. 

A prompt similar to the following is displayed. 



The protocol for link 1 is N5 


Note: Setting unused channels out of service allows the unit to 

ignore circuits that are not operational. When a channel is out of 

service, all messages from the SS7 side are ignored. In addition, the 

N5 line signals are set to idle and no messages are sent to the SS7 

side. 


The specified channels will be placed into service. One of the 

following prompts appears: 

• A prompt similar to the following is displayed. 

Destination country code for calls to N5 (current) : 

Enter up to 3 digits: 

4 Type the country code and press Enter. 

Calls coming from the C7 direction toward the N5 with the 

country code entered here will have a KP1 attached. Calls with 

different country codes will have a KP2 attached and will be 

processed only if transit calls to N5 are enabled (in Step 5). The 

following prompt appears. 

Transit calls to N5 enabled ? (y or n) : 

5 If transit traffic will not be allowed, answer n. 

If transit traffic will be allowed, answer y. 



Note: Calls to N5 with a country code different from the code 

specified in Step 4 are assumed to be transit traffic. 


Use Calling Party Category to set N5 language digit? (y or n) : 

 


a 

Answer y if the language digit will derive from the calling party 

category. 

The following prompt appears. Go to Step 8. 

Prefix to be stripped from digits before sending to N5 (current) 

: 011 


b Otherwise, answer n. 

Note: Calling party categories 7 and 13 (test call) will cause the call 

to be cleared with cause 31. 

The following prompt appears. This prompt allows a fixed 

language digit to be used. 

N5 side outgoing language digit (current) : 

Enter up to 1 digit: 



7 Type the fixed language digit for calls originating from the N5 side, 

and press Enter. (Or just press Enter to accept the default.) 


Prefix to be stripped from digits before sending to N5 (current) 

: 011 


8 If digits in front of the country code need to be removed, enter those 

digits here. 

Note: This field may be set to undefined by entering a hyphen (-). 


Digits that cause C11 to be sent to N5 (current) : 


Note: Code 11 is used to signal to an operator. 

9 Enter the digit string that is used to call the operator with the C11 

code. 


Digits that cause C12 to be sent to N5 (current) : 




Note: Code 12 is used to signal to an operator. 

10 Enter the digit string that is used to call the operator with the C12 

code. 


Language digit expected from N5 [* = any] (current) : 


11 If only calls with a particular language digit will be accepted, then 

enter that digit here. Otherwise enter an asterisk (*) to accept calls 

from N5 with any language digit. This field may be set to undefined 

by entering a hyphen (-). 


Transit calls FROM N5 enabled ? (y or n) : 

12 In N5, calls with a KP2 attached are defined as transit calls. Do one 

of the following: 

a 

Answer n (the default) for these calls to be cleared with a busy flash. 


Digits to prepend in non-transit calls coming from N5 (current) : 


Note: Calls with a KP1 attached are defined as non-transit calls. 



b 

Answer y to allow these calls to pass to the C7 side. 


Digits to prepend in transit calls coming from N5 (current) : 


Note: Calls with a KP2 attached are defined as transit calls. 

13 If you wish to prepend up to three digits to transit calls, enter that 

digit string here. This field may be set to undefined by entering a 

hyphen (-). 


Digits to prepend in non-transit calls coming from N5 (current) : 


Note: Calls with a KP1 attached are defined as non-transit calls. 

14 If you wish to prepend up to three digits to non-transit calls, enter 

that digit string here. This field may be set to undefined by entering 

a hyphen (-). 


Use Calling Party Category from template? (y or n) : 




a 

b 

Answer y to use the Calling Party Category specified in the 

configured IAM template. 

Answer n for the Calling Party Category to derive from the N5 

language digit. 

Whether you answer yes or no, the following prompt appears. 

Digits to send when C11 is received from N5 (current) : 


16 Enter the digit string to send when the C11 operator code is received 

from N5. This field may be set to undefined by entering a hyphen (-). 


Digits to send when C12 is received from N5 (current) : 


17 Enter the digit string to send when the C12 operator code is received 

from N5. This field may be set to undefined by entering a hyphen. 


Template # for default IAM ? (1 - 5; current=1) : 

Note: This template provides values for many parameters that are 

required on the SS7 side but are not specified by the CAS protocol. 

18 Type the IAM template number to use, and press Enter. 




Template # for default ACM ? (1 - 5; current=1) : 

Note: This template provides values for many parameters that are 

required on the SS7 side but are not specified by the CAS protocol. 

19 Type the ACM template number to use, and press Enter. 


Use user-defined caller ID (ANI) in calls from N5? (y or n) : 

y 

Note: N5 does not support caller ID (ANI); any ANI on calls 

coming toward N5 are discarded. However, some networks require 

that an ANI be present in all calls. This feature allows a fixed ANI to 

be associated with each channel in calls originating from N5. 


a To use the caller ID that is already present in the call, answer n. 


Generate ringback tone for N5 originated calls? (y or n; 

current=n) : 

b To use a caller ID that you specify, answer y. 




Enter user-defined ANI (current): 


21 Type the ANI you want calls to use, and press Enter. 


Generate ringback tone for N5 originated calls? (y or n; 

current=n) : 


a 

Answer y and press Enter to have the SP230 generate a ringback to 

the N5 caller. This lets the caller know the call is going through. This 

may be desirable in certain situations—for example, if the SP230 is 

connected to a private branch exchange (PBX) that does not generate 

its own ringback tone. This is normally an end-office function. 

Note: The ringback tone occurs after all digit signaling has been 

completed and the indication is that the destination party is ringing. 

The ringback tone is 450 Hz, cycling at 2 seconds on, 4 seconds off. 

b 

Answer n and press Enter to pass through end-office ringback to the 

N5 caller while waiting for the call to be answered. 

Whether you answer y or n, the user> prompt is displayed. 

23 Perform Step 1 through Step 22 until each N5 channel that this unit 

will use has been placed into service.
