System Selection; Fiber Remote Ipe Site Planning - Nortel 1000 Manual

System selection

Determine the type of Fiber Remote IPE enclosure. This selection can 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, select the modular column. If planning
a wall-mounted system, select the cabinet.
In some applications where non-blocking or low blocking traffic
considerations are important, it is necessary to limit the number of
peripheral cards supported by each Fiber Peripheral Controller card. For
a non-blocking condition, the 120 voice/data timeslots support seven or
eight 16-port line cards. Each additional line card in the IPE module or the
wall-mounted cabinet increases call blocking under high traffic conditions.
Refer to Communication Server 1000M and Meridian 1 Large System
Planning and Engineering (NN43021-220) () to calculate traffic.
The system type can also be dictated by the number of ports required at
the remote site. The modular column configuration supports 16 line cards
and provides a maximum of 256 ports. This column can be expanded by
adding a second IPE module to support an additional 256 ports. Each IPE
module requires a Fiber Peripheral Controller card at the remote site and a
corresponding Fiber Superloop Network card at the local site.
In addition to line cards, the Fiber Remote IPE supports all the cards
that do not require external connection to the local common or network
equipment.
The wall-mounted configuration supports 10 line cards. The wall-mounted
system can be used if the system size requirement is less then ten IPE
cards. To expand this type of system beyond ten IPE cards, add an
expansion cabinet adjacent to the main cabinet, and install up to six IPE
cards into the first six IPE card slots of the expansion cabinet.

Fiber Remote IPE site planning

When selecting a site for the Fiber Remote IPE, consider the number of
ports currently required at the site and the possibility of expansion to meet
future needs. As well, consider environmental, power, and cable-routing
requirements.
Environmental requirements
Fiber Remote IPE equipment conforms to the same environmental
requirements as the rest of the system equipment. Temperature, humidity,
and altitude for equipment operation should not exceed the specifications
shown in Table 4 "Environmental requirements" (page
