MX2820 System Manual
Table 7-7 provides the configuration recommendations for circuit recovery.
During a module switch, service interruption is experienced on
both the DS3/STS-1 and T1/E1 connections. However, since the
standby module remains framed to the incoming signal at all
times, it is a minimal interruption.
