ESAM is intended to be used, primarily, in the case of an interruption in
service from the T1 carrier links serving MCR systems. A two-position
faceplate switch on the RMI, like the LMI, sets ESAM mode as always
active or requires that the ESAM switchover be determined through each
location's MMI configuration. This does not change the normal operation of
MCR's telephones or trunks. During ESAM mode, however, the following
changes take place:
•
up to 16 digital telephones, connected to the same XDLC, may be
