TimeProvider 2300/2700 CLI Command Set
– CCS, CAS, or freq 2048KHz for E1
– D4, ESF, or freq 1544KHz for T1
CRC state for E1
SSM Bit position for E1
All the configurations provisioned by this command apply to the T1/E1 input port
only when the IO-direction of the port is configured as an Input with the
set
port-control t1e1 io input
command.
Command Syntax:
To set the frametype, CRC, and SSM bit position for E1 Input:
set input e1 frametype t1e1 {ccs | cas | freq2048kz}
set input e1 crc t1e1 {enable | disable}
set input e1 ssmbit t1e1 {4 | 5 | 6 | 7 | 8}
To set the frametype for T1 Input:
set input t1 frametype t1e1 {d4 | esf | freq1544kz}
Example 1:
To provision the T1/E1 port for E1 input with CAS frametype, CRC enabled, with
SSM bit position of 6:
TP2700> set input e1 frametype t1e1 cas
TP2700> set input e1 crc t1e1 enable
TP2700> set input e1 ssmbit t1e1 6
Example 2:
To provision the T1/E1 port for T1 input with D4 frametype:
TP2700> set input t1 frametype t1e1 d4
Remarks:
– The port state, IO direction (input or output) and signal type (e1 or t1) are
configured by
set port-control command.
– No user provisioning for line code when the port is set as input by
set
port-control
command. It is hardcoded as HDB3 for E1 and B8ZS for
T1 (zs=enable, i.e., zero suppression is on), and in this way, the input port
will accepts both HDB3 (B8ZS for t1) and AMI code.
