4.146 chg-t1

Use this command to change an interface for a T1 card in the system. T1 cards consist of /E5-E1T1-B cards used as T1 or ST-HSL-A cards.

Parameters

loc (mandatory)
The card location as stenciled on the shelf of the system.
Range:
1101 - 1108, 1111 - 1112, 1201 - 1208, 1211 - 1218, 1301 - 1308, 1311 - 1318, 2101 - 2108, 2111 - 2118, 2201 - 2208, 2211 - 2218, 2301 - 2308, 2311 - 2318, 3101 - 3108, 3111 - 3118, 3201 - 3208, 3211 - 3218, 3301 - 3308, 3311 - 3318, 4101 - 4108, 4111 - 4118, 4201 - 4208, 4211 - 4218, 4301 - 4308, 4311 - 4318, 5101 - 5108, 5111 - 5118, 5201 - 5208, 5211 - 5218, 5301 - 5308, 5311 - 5318, 6101 - 6108, 6111 - 6118
t1port (mandatory)
T1 port number

The value must be a T1 port that has already been configured with a T1 interface on the specified T1 card.

Range:
1 - 8

Any 2 of the 8 ports on an E5-E1T1-B card can be specified when the card is used as an ST-HSL-A card.

Any 1 of the 8 ports on a card can be specified when the card is used as an ST-HSL-A card.

encode (optional)
Indicator for use of B8ZS or AMI encoding/decoding.
Range:
b8zs
ami
Default:
No change to the current value
framing (optional)
Indicator for framing format. esfperf is the framing format with performance monitoring.
Range:
sf, esf, esfperf
Default:
No change to the current value
ll (optional)
T1 cable length in feet between the EAGLE and the connecting node.
Range:
0 - 655
Default:
No change to the current value
minsurate (optional)
Minimum signal unit rate. The minimum number of SUs present on a link that are uniformly distributed.
Range:
400 - 1600
Default:
No change to the current value
t1tsel (optional)
This parameter specifies the timing source for a T1 card.
Range:
line - slave timing source
external - master timing source
Default:
No change to the current value

Example

chg-t1:loc=1205:t1port=1:encode=ami

chg-t1:loc=1205:t1port=2:encode=b8z:ll=250s

chg-t1:loc=1205:t1port=1:minsurate=1000

chg-t1:loc=1205:t1port=1:encode=ami:t1tsel=external

Dependencies

At least one optional parameter must be specified.

The card location specified by the loc parameter must be equipped.

The E1/T1 table must be accessible.

The Card (IMT) table must be accessible.

The card specified by the loc parameter must be a LIMT1 card type.

The port specified by the t1port parameter must have already been configured with a T1 interface on the specified T1 card.

All signaling links that are serviced by the specified T1 card must be deactivated before the values for the encode, t1tsel, ll, and framing parameters can be changed.

The shelf FAN bit must be turned ON for the shelf on which an E5-E1T1-B card is provisioned and present. The system checks the shelf FAN bit when an E5-E1T1-B card is present in the specified odd card location (loc parameter) and the chanbrdg=on parameter is specified.

HIPR2 cards must be equipped in card locations xy09 and xy10 (x is the frame, y is the shelf) on each EAGLE shelf that contains one or more /E5-E1T1-B cards. The system checks for HIPR2 cards when the chanbrdg=on parameter is specified for /E5-E1T1-B cards.

The following card locations cannot be specified in the loc parameter: 1113 - 1118 (E5-MASP and E5-MDAL cards), or xy09 and xy10 where x is the frame and y is the shelf (MUX cards).

The linkclass=unchan parameter must be specified (see the ent-t1 command) before the minsurate parameter can be specified.

The ST-HSL-A feature must be turned on before the framing=esfperf parameter can be specified.

Notes

External timing is derived from the EAGLE High-Speed Master Clock (1.544 MHz for T1 or 2.048 MHz for E1): therefore, the Master Timing feature is required. Line timing is derived from its received data stream, if present.

Output
