Engineering guidelines

General system engineering guidelines for Large Systems are described
in Communication Server 1000M and Meridian 1 Large System Planning
and Engineering (NN43021-220) () . The following information deals
specifically with engineering guidelines for the Fiber Remote Multi-IPE
Interface planning and implementation. It also describes the fiber-optic
interface specifications and fiber-optic link characteristics.
Remote IPE capacity
The local system's physical capacity depends on the system's
configuration and size. Large Systems are designed to provide port
capacities from tens to thousands of ports. These ports are normally local;
however, by implementing Fiber Remote Multi-IPE Interface, many of
these ports can be located at one or more remote sites.
The overall maximum system capacity does not change by installing Fiber
Remote Multi-IPE Interface units to support distributed intelligent peripheral
equipment (subscriber loops) at Remote IPE sites. Fiber Remote Multi-IPE
Interface allows you to distribute the intelligent peripheral equipment at
long distances from the local system and provide the same functions and
features to remote subscribers as to local subscribers.
The Fiber Remote IPE capacity can be tailored according to port capacity
requirements at the remote site. When planning a Remote IPE site, you
must determine the number of IPE cards required to support the existing
and future traffic needs and the call blocking tolerance.
A Remote IPE column consists of a pedestal, from one to four IPE
modules, and a top cap. One IPE module supports up to 16 line cards,
or 256 ports if each line card has 16 ports (other IPE cards may have

Power LED. Indicates that the Fiber Remote Multi-IPE Interface passed
self-test and the AC/DC power converter powering the Fiber Remote
Multi-IPE Interface is operating correctly.
Red Alarm LED. Indicates a near-end fault condition. This near-end
fault condition activates the Yellow Alarm LED at the far-end Fiber
Remote Multi-IPE Interface.
Yellow Alarm LED. Indicates a far-end alarm condition. This alarm LED
is activated by a far-end fault condition (when the Red Alarm LED is
activated at the far-end).
Maintenance In Progress LED. Indicates that a function in the
fiber-optic link or one or more superloops have been disabled using
maintenance commands. The LED will also be lit if a service-effecting
off-line diagnostic test is in progress.
