ATLAS 550 System Manual Section 4 User Interface Guide
MODULES (E1/PRA-1) > CONFIGURATION > PRT
Write security: 3; Read security: 5
Displays the port number.
MODULES (E1/PRA-1) > CONFIGURATION > PORT NAME
Write security: 3; Read security: 5
Accepts any alpha-numeric name up to 16 characters long, to uniquely identify the E1/PRA port.
MODULES (E1/PRA-1) > CONFIGURATION > NFAS
Write security: 3; Read security: 5
If enabled, the network interface receiver requires the NFAS word (TS0 0 in odd frames) and the FAS word
(TS0 0 in even frames) for frame sync. When disabled, only the FAS word is needed for frame sync.
MODULES (E1/PRA-1) > CONFIGURATION > TS16 MF
Write security: 3; Read security: 5
If enabled, the receiver requires MFAS word in TS16 to achieve sync (CAS signaling). The transmitter
outputs MFAS word in TS16 (CCS signaling).
MODULES (E1/PRA-1) > CONFIGURATION > CRC-4
Write security: 3; Read security: 5
Transmits the CRC-4 checksum bits in the outgoing E1 data stream, when enabled. Also, checks the
received signal for errors.
MODULES (E1/PRA-1) > CONFIGURATION > AUTO ALARM
Write security: 3; Read security: 5
Transmits a remote alarm when framing is lost (when Red Alarm Generation is on), and transmits an AIS
alarm when all ones are received (when RCM AIS Generation is on).
MODULES (E1/PRA-1) > CONFIGURATION > CODE
Write security: 3; Read security: 5
Allows selection of line coding. HDB3 is normally the only coding method used on public networks. AMI
may be selected for testing purposes.
MODULES (E1/PRA-1) > CONFIGURATION > TS0 SPARE
Write security: 3; Read security: 5
TS0 bits Sa4 through Sa8 in frames not containing the Frame Alignment Signal may be used in specific
applications, but should be set to 1s when crossing an international border. Enter a decimal number whose
5 LSB (least significant bits) are to be used for all Sa4 and Sa8 bits. Refer to CCITT G.704 for more
information.
