Demand test descriptions and error codes - Avaya Support

TN464 circuit packs support the following:
● Digital Tie, CO, and DID trunks
● DS1 off-premises (OPS) lines
● Narrowband and wideband access endpoint ports
● ISDN-PRI trunks and accompanying signaling chel
● PRI endpoint ports (PE-BCHL) and accompanying signaling chel
The TN464 supports digital Tie, CO, and DID trunks, and OPS lines. On-board firmware
performs call control signaling for the Tie, CO and DID trunks and OPS lines. ISDN-PRI trunk
and PRI-endpoint signaling (Q.921, Q.931) is received and generated by system software and
is transmitted on a system link through the TN1655 Packet Interface and packet bus to the
UDS1 where it is placed on the D chel. Signaling over the DS1 link has to be synchronized
between the transmitting and receiving ends to ensure error-free communication. See SYNC
(Port Network Synchronization) for details.
Each trunk, line, or endpoint has its own maintenance strategy, but all depend on the health of
the UDS1 Interface circuit pack. See the following Maintenance Objects for details:
TIE-DS1 (DS1 Tie Trunk)
CO-DS1 (DS1 CO Trunk)
DID-DS1 (Direct Inward Dial Trunk)
OPS-LINE (DS1 Off-Premises Station Line)
ISDN-TRK (DS1 ISDN Trunk)
ISDN-PLK (ISDN-PRI Signaling Link Port)
ISDN-SGR (ISDN-PRI Signaling Group),
WAE-PORT (Wideband Access Endpoint Port)

Circuit Pack Administration and Options
The DS1 configuration for each circuit pack is administered on the DS1 Circuit Pack screen. Bit
Rate is set to 1.544 Mbps for 24-chel systems, and 2.048 Mbps for 32-chel systems. Country
Protocol is used to drive layer-3 protocol decisions based on PRI specifications for a given
country (not those related to specific features). Different UDS1 circuit packs may be
administered with different Country Protocols, allowing the switch to act as a gateway between
two incompatible ISDN-PRI implementations (for example, between two different countries). US
systems use country protocol 1.
Set Near-End CSU Type to other for no CSU installed or for an external CSU such as an ESF
T1 CSU, or set to integrated for the 120A1 CSU module or the 401A T1 sync splitter. Setting
the field to integrated causes additional fields to appear for administering the Enhanced
Integrated CSU module. Set E1 Sync-Splitter to y if a 402A or 403A E1 sync splitter is used to
provide timing to an ATM switch. Set Echo Cancellation to y if the echo cancellation
right-to-use feature is enabled and the TN464GP/TN2464BP or higher suffix board is to supply
echo cancellation.
