Line Trunk Controller; Intelligent Peripheral Equipment (Ipe) - Nortel SL-100 Product Manual

62 Meridian SL-100 peripherals
minimum concentration for a fully-provisioned Line Concentrating Module
(approximately 35:1) involves concentrating 640 line terminations onto the
maximum six 2 Mbps links between the Line Group Controller and the Line
Concentrating Module. This would be suitable for business lines.
Line Concentrating Modules support intraswitching (that is, the speech path
between the two lines supported by the same Line Concentrating Module is
through-connected at the Line Concentrating Module, not through the ENET
switching matrix). Note, however, that call processing is still performed by
the Core, so the Line Concentrating Module still needs to communicate with
the Core through ENET and the Line Group Controller for call establishment
and clearing.
Line Concentrating Modules contain a Ringing Generator card used to
provide ringing to the subscriber lines. This is duplicated for reliability. An
enhanced Ringing Generator card is available that has dipswitches that can
be used to control the ringing cadence generated by the card.

Line Trunk Controller

The Line Trunk Controller is a peripheral module that is a combination of
the Line Group Controller and the Digital Trunk Controller and provides all
the services offered by both. It supports the Line Concentrating Module
and AB trunks.
The Line Trunk Controller-ISDN (LTC-I) is a peripheral module that is a
combination of the Line Group Controller and the Digital Trunk Controller
and, like the LTC, provides all the services offered by both. The LTC-I is
wired to support up to eight Line Concentrating Modules or Digital Line
Modules (DLM) requiring up to 20 DS-30A trunk ports and 16 DS-30 line
ports.

Intelligent Peripheral Equipment (IPE)

The Intelligent Peripheral Equipment (IPE) Module on the Meridian SL-100
provides the capability for customers to use M3900 Series Telephones,
Meridian Digital Telephones and lineside features and services. Since the
IPE is common to both the Meridian 1 and Meridian SL-100 systems, users
who move from Meridian 1 systems to the Meridian SL-100 are already
familiar with telephone equipment and many of its features and services.
In addition, customers who upgrade from Meridian 1 systems to Meridian
SL-100 systems can capitalize on their initial investment in both terminals
and peripheral equipment.
