Digital Expansion Interface
Installing the following hardware on the Inter-Tel 5000 platform incorporates digital capability
into the Internet Protocol (IP)-based Inter-Tel 5000 platform.
Digital Expansion Interface Unit
Each Digital Expansion Interface (DEI) unit and its associated hardware and software provides
digital capability. Dimensions of the DEI are the same as the Inter-Tel CS-5200/5400 Commu-
nication Servers chassis. Refer to "Inter-Tel CS-5200/5400 Communication Servers Chassis
Dimensions" on
Digital Endpoint Module
Each Digital Endpoint Module (DEM-16) provides 16 circuits for connecting Executive, Pro-
fessional, Standard, and Associate Display phones, Axxess and Eclipse Basic Digital phones,
Model 8500, 8520, and 8560 phones, or Single-Line Adapters (SLA) to the system.

Two loop start trunk circuits in a single port, preprogrammed for connection to the local
telephone company central office (CO) [local exchange in Europe]. These circuits,
along with the two built-in single line circuits form the Inter-Tel 5000's Power Fail
Bypass feature. The default settings can be reprogrammed by a certified Inter-Tel tech-
nician.
Two single line circuits in a single port, preprogrammed for connecting analog phones.
These circuits, along with the two built-in loop start trunk circuits form the Inter-Tel
5000's Power Fail Bypass feature. The default settings can be reprogrammed by a certi-
fied Inter-Tel technician.
Power Fail Bypass: If power to the system is interrupted, an inter-
nal electrical relay automatically connects the two single line circuits
with the two loop start trunks to provide direct connection to CO/local
exchange trunk dial tone.
IMPORTANT
Under normal operating conditions, the circuits can be programmed
and used the same as any loop start/local exchange trunks or single
line circuits. However, when system power fails, the circuits automat-
ically connect, regardless of any reprogramming that may have been
done.
One RCA socket for connection of an external paging system.
One 1/8-inch coaxial stereo socket for connection to a local music source for imple-
menting Music-On-Hold and/or Background Music.
One DB-15 socket for connection to an external Voice Processing Unit or Enterprise
Messaging Unit.
One 10/100Base-T Ethernet socket on the Processor Module (PM-1).
Three bays for inserting trunk circuit modules. The trunk module bays can be equipped
with any suitable combination of loop start/CO/local exchange trunks, T1, T1/PRI, or
E1/PRI multi-channel trunks, or BRM-S trunks. Each LSM-2 module supports two loop
start trunks; each LSM-4 module supports four loop start trunks; each T1/E1/PRI mod-
ule supports one span; and, each BRM-S supports two BRI trunks.
One power cord socket.
