Description of
IPE‘UEM
(NT8D37AA/DC)
The NT8D37 IPE backplane (NT8D3701) contains 16 card slots. Slots O-15
are for line cards. Slot 16 is for miscellaneous. The Controller Card is
situated near the center of the module, between slot 7 and slot 8.
If one or two superloops are to be served, use
Cont-3
If three or four
superloops are to be served, use Cant-4. The Controller-4 card is required
when a large number of Integrated Voice and Date
(ND)
lines are non-
blocking and when they require, on average, more than four Digital Line
Cards (Dgtl LCs) per IPE DEM.
The nominal capacity.of the IPE UEM is 256 Integrated Voice and Data
(IVD) or analog lines; however, a typical configuration of the PE UEM
includes a combination of line, trunk, and
Digitone
Receiver cards which
provide about 160 lines with the appropriate trunks.
