256x6 = 1536 CCS. From Table 3, this number still requires three E1
carriers.
4.
Calculate traffic, card slots and carriers for the second IPE module or
Carrier Remote IPE cabinet:
Remaining lines: 400-256 = 144
Card slots: 144/16 = 9
Traffic: 144x6 = 864 CCS
Carriers required: From
39), 2 E1 carriers can handle 1384 CCS which should be enough to
serve the 864 CCS from 144 lines (but one carrier at 575 CCS is not
quite enough).

Configuration Summary:
IPE1 (IPE module): 6 CCS/line, 256 lines, 16 cards, three E1 carriers.
IPE2 (Carrier Remote IPE cabinet): 6 CCS/line, 144 lines, 9 cards,
twoE1 carriers.

System planning and ordering

CS 1000M Large Systems and Meridian 1 Large Systems provide the
user with a variety of system size and feature options. To select a system
option that will best suit current and future communication needs, carefully
plan the system. Contact the Nortel representative or Nortel distributor to
help plan the system.
If installing a new system with Carrier Remote IPE, refer to Communication
Server 1000M and Meridian 1 Large System Planning and Engineering
(NN43021-220) () for overall system information. To obtain specific
planning and ordering information for T1 and E1 carrier links interfacing
with network and peripheral cards, see the following sections.

System selection

Determine the type of Carrier Remote IPE enclosure. This selection may
be dictated by the installation preference, blocking considerations, and the
number of IPE cards required at the remote site.
If planning a floor-standing system, use the Carrier Remote IPE column
or the pedestal mounted Carrier Remote IPE cabinet. If planning a
wall-mounted system, use the Carrier Remote IPE cabinet.
In some applications where nonblocking or low-blocking traffic
considerations are important, it is necessary to limit the number of
peripheral cards supported by each Remote Carrier Interface card.
For a nonblocking condition, the 63 voice/data timeslots for three T1
carriers support four 16-port line cards; the 81 voice/data timeslots for
three E1 carriers support five 16-port line cards. Each additional line
