Mini-Carrier Remote
Description, Installation, and Maintenance
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 ESAM switchover be determined through each location’s
MMI configuration. This does not change 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
enabled;
•
ESAM is indicated on the display of configured telephones;
•
station-to-station dialing capability is enabled;
•
a 2- to 5-digit MMI-programmable ESAM extension takes effect,
— all 16 telephones must have extensions of equal length,
— default length is 4,
— the extensions default to 4100 - 4115;
•
feature key 0 accesses the primary line;
•
feature key 1 accesses a secondary line,
— the secondary line will have the same Directory Number, DN, as the
primary line;
•
an independently-programmable key transfers calls,
— this key is programmed via the MMI,
— the default key is 2;
•
an independently-programmable key for outgoing calls,
— this feature is programmed via the MMI,
— the default key is 9;
•
MMI-configurable do-not-ring feature may be used to block incoming
trunk calls from ringing to a given telephone (see, “Do-not-ring mode”
on page 29),
— as a default setting, incoming trunk calls ring to all telephones;
•
the MMI will allow up to 8 XUT trunks to be enabled,
