Remote IPE Card Compatibility
Survivability Requirements
If any of the T1 carrier links (or portion of them) fail during normal operation,
MCR will provide “limited PBX-like” service to some of the remote
telephones until the link failure is corrected. This feature requires the remote
site to be equipped with analog trunk circuits (up to eight) that are terminated
to a single Universal Trunk (NT8D14) located in the remote cabinet.
The remote cabinet must also be equipped with a Digital Line Card
(NT8D02) and may be configured with up to 16 Meridian Digital Telephones.
For a list of the models that support this feature, see Table 1 on page 26.
Traffic Capacity
Each LMI and RMI card pair can support a portion of one T1 carrier link, the
full twenty-four channels of the T1 carrier link, or two full T1 carrier links.
The LMX cards interface to the T1 through the LMI card, therefore, T1
provisioning is not required for these cards. The minimum number of T1
channels required for LMI/RMI card pairs is 3 out of twenty-four. This means
2 are used for proprietary signaling purposes and the third is used for standard
voice/data traffic. If 2 full T1’s are equipped, two channels from each link are
used for signaling and the balance are used for voice/data traffic.
Blocking
Call Blocking occurs when there are more calls than available time slots. For
ACD sets, plan one time slot per set. For non-ACD sets, plan according to
usage. See “Time slot assignment and hold” on page 23, and “Blocking” on
page 24.
