Without these patterns on the idle timeslots, instability of the T1 signaling link may occur. All other idle timeslots that are not dropped by the EAGLE must contain an idle pattern provided by the remote network elements connected to both T1 ports (bridging master and slave). Idle patterns on the shadow channels, that is, the timeslots located on the bridging slave T1 port that have been not been dropped from the bridging master T1 port, are provided by the EAGLE.

Both the bridging master and slave T1 ports are using an external clock source (using the t1tsel=external parameter when provisioning the channel bridged T1 port with either the ent-t1 or chg-t1 command).Īny other methods used for timing could cause problems on the T1 trunk and are not be supported.

The bridging slave T1 port is automatically provisioned with the same attributes as the bridging master T1 port. When provisioning channel bridged T1 port, only the bridging master T1 port is provisioned with the ent-t1 or chg-t1 command.

The bridging master T1 port and the bridging slave T1 port use timing recovered from each other (using the t1tsel=recovered parameter with either the ent-t1 or chg-t1 command).

This may be accomplished in one of the following ways: In order to use channel bridging without facility errors, both T1 ports (bridging master and slave) must be synchronous (timed off the same clock source).

There is a 1 to 1 correspondence between the timeslots on the bridging master and slave T1 ports.

This interface is a bi-directional interface so data is also able to enter the bridging slave (even) T1 port and leave the EAGLE through the bridging master (odd) T1 port. Table B-2 Channel Bridging T1 Port Pairing Odd Numbered T1 Port (Bridging Master)Įven Numbered T1 Port Bridged to the Odd Numbered T1 Port (Bridging Slave)īy pairing T1 ports, the adjacent even numbered T1 port could be used to allow data received on the bridging master (odd) T1 port to reach downstream network elements.
