Intelligent Peripheral Equipment remote location
In a local operating environment, IPE can be housed up to 15.2 m (50 ft)
from the Common Equipment. IPE installed in a remote location extends
this range, allowing approximately 112.6 km (70 miles) between local and
remote facilities.
This extension is achieved by converting multiplexed loop signals to a form
compatible with the commonly used T-1 type digital transmission system.
Refer to
of IPE cards for use at the remote site.
Any medium that conforms to the DS-1 format (1.544 Mbps) can be used to
link local and remote sites, including digital microwave radio and fiber-optic
transmission systems.

Terminal equipment

Large Systems support a wide range of telephones, including multiple-line
and single-line telephones, as well as digital telephones with key and
display functions and data transmission capabilities. A range of options for
attendant call processing and message center applications is also available.
In addition, a number of add-on devices are available to extend and enhance
the features of telephones and consoles. Add-on devices include key/lamp
modules, lamp field arrays, handsets, and handsfree units.
For more information refer to Telephones and Consoles Fundamentals
(NN43001-567) and IP Phones Fundamentals (NN43001-368).
Digital telephones
Analog-to-digital conversion takes place in the digital telephone itself, rather
than in the associated Peripheral Line card. This eliminates attenuation,
distortion, and noise generated over telephone lines. Signaling and control
functions are also handled digitally. Time Compression Multiplexing (TCM)
is used to integrate the voice, data, and signaling information over a single
pair of telephone wires.
For applications where data communication is required, Meridian 1 digital
telephones offer an integrated data option that provides simultaneous voice
and data communication over single pair wiring to a port on a digital line
card.
