1 IPE product overview
The Intelligent Peripheral Equipment (IPE) provides a common peripheral for
the Meridian SL-100 product line. The IPE also provides a single common
peripheral with common line cards for the SL-100 system, Meridian 1 system,
and Meridian SuperNode system, as well as a cost-effective solution for
upgrades and extensions.
The IPE is a single-shelf module containing a controller card and 16 slots
available for analog and integrated voice and data (IVD) digital lines. IPEs are
packaged as modular, stackable units. Up to four IPEs can be contained in one
IPE column (IPEC). The Meridian power distribution cabinet (MPDC)
provides an external -48 V (dc) power supply to the IPE. The MPDC provides
dc power to the IPE lineup, which is separate from the standard SL-100 lineup.
The following figure shows four IPE modules contained in one IPEC. This
type of architecture and peripheral consolidation allows easy installation of
equipment and provides a flexible, cost-effective method of growth.

Refer to Chapter 2, “IPE architecture", for additional information about the
IPEC hardware and configurations.
Status reporting with XSM functionality
Each IPEC requires one extended system monitor (XSM) that can be
configured as a master XSM or as a slave XSM. (Refer to Chapter 2 for
details.) One master XSM supports up to 64 columns using a daisy chain of
serial communication links. Thus, one master XSM can potentially support up
to 256 (64 x 4) IPE modules. The master XSM reports status over an RS-232-C
