Trunk cards
Figure 12: DS-30X loop data format
DS-30Y network loops extend between controller cards and superloop network cards in the
common equipment, and function in a manner similar to DS-30X loops. See
Figure 13: Network
connections to IPE modules
on page 64.
Essentially, a DS-30Y loop carries the PCM timeslot traffic of a DS-30X loop. Four DS-30Y
network loops form a superloop with a capacity of 128 channels (120 usable timeslots).
See Communication Server 1000M and Meridian 1 Large System Planning and Engineering
(NN43021-220) for more information about superloops.
Card LAN link
Maintenance communication is the exchange of control and status data between IPE line or
trunk cards and the CE CPU by way of the NT8D01 Controller Card. Maintenance data is
transported via the card LAN link. This link is composed of two asynchronous serial buses
(called the Async card LAN link in
Figure 11: Typical IPE trunk card architecture
on page 61).
The output bus is used by the controller for output of control data to the trunk card. The input
bus is used by the controller for input of trunk card status data.
