Chapter 3 Provisioning and Operating the SSU-2000e
Initial Provisioning
5. Set the framing type for each input port. Provision DS1 signals to either ESF or
D4; provision E1 signals to CAS or CCS.
ICS command:
Type
INPUT 1Ay-z FRAME ESF|D4
where y is the slot number and z is the port number. Select either ESF or D4 as
appropriate. Repeat this command as needed for each slot and port.
TL1 command:
See Step 8, below.
6. Provision the Zero Suppress for each input port to On or Off as appropriate.
ICS command:
Type
INPUT 1Ay-z ZS ON|OFF
where y is the slot number and z is the port number.
TL1 command:
See Step 8, below.
7. Provision the Cyclic Redundancy Check (CRC) for each input port to On or Off.
ICS command:
Type
INPUT 1Ay-z CRC ON|OFF
where y is the slot number and z is the port number.
TL1 command:
See Step 8, below.
8. Provision the Synchronization Status Message (SSM) for each input port to On or
Off. When set to On, the SSU-2000e reads and interprets the SQL on the
reference. If the reference does not include an SSM, the SQL is defined as STU.
ICS command:
Type
INPUT 1Ay-z SSM ON|OFF
and z is the port number.
For E1 signals, you must define the bit position:
Type
INPUT 1Ay-z SSM [4–8]
TL1 command:
SET-PRMTR-INPUT::S1Ay[-z]:123::,,,ESF|D4|CCS|CAS|1|1.544|
2.048|5|10,ssm,zs,crc,,bit;
where y is the slot number and z is the port number and the numbers indicate the
input frequency in mega Hertz; ssm, zs, and crc are ON or OFF, as appropriate.
Bit indicates the position (4–8) of the SSM in E1 signals.
