Suggestions for
Changing the
Maintenance
State of Channels Use the following information to help you determine why a channel may be
placed in a given maintenance state.
Manoos E1/T1 Channels Using E&M Protocol
The following suggestions apply only to individual MANOOS E1/T1 channels
using the
E&M protocol . Other E1/T1 protocols provide the ability to remove
individual channels from service.
At times, you may want to limit the number of calls the system handles by
removing some of the E1/T1 channels from service. Note that removing
E1/T1 channels, however, may negatively impact the system if the switch
uses an inappropriate hunting pattern.
The E&M protocol does not allow you to remove individual channels from
service. If a switch using the E&M protocol does not recognize that a channel
is in a MANOOS state, it continues to route calls to that channel.
The system thus returns a busy signal to the caller if the switch directs the
call to a MANOOS channel. For some hunting patterns (for example, those
using a round–robin pattern for new call delivery), this is not desirable. With a
round–robin style of delivery, the switch routes a new call to the next channel
in the hunt group. When the switch reaches the end of the group, it starts
