INTEGRATED CORDLESS
The Integrated Cordless (IC) is a digital cordless tele-
phone solution complying to the DECT standard pro-
viding wireless connection for up to 108 portables with
the A-protocol and 210 portables in GAP-protocol ap-
plications. Several components comprise a complete
system.
After the system has been physically installed use
RASC and the Cordless System Manager (CSM) for
initialization, maintenance, updating, fault finding and
when possible to recover the PBX from errors. The
CSM is orderable under LZYNB 201 01 R6A or higher
for the A-protocol and LZYNB 201 05 R1B or higher for
GAP applications.

Board Descriptions
6.1.1
IC-Control Unit (IC-CU)
The IC-CU_ is the control board supporting the A-pro-
tocol and up to 7 IC-LUs located in the same cabinet.
Up to 56 BSs can be connected. The board offers 2
connections for:
•
the Cordless System Manager (on a PC)
•
a printer to log errors.
6.1.2
IC-Control Unit2 (IC-CU2)
The IC-CU2 is the control board supporting the DECT
GAP-protocol and up to 7 IC-LUs located in the same
cabinet. The IC-CU2 includes 8 voice channel units
(SPU as on the IC-LU) and is equipped with 4 BSs in-
terfaces. With the maximum of 7 IC-LUs up to 60 BSs
can be connected.
The wiring distance with remote power feeding to the
BSs using only the serial communication wires SC0
and SC1 is limited to 400m. For greater line lengths
additional Express Power feeding Pairs (EPP) need to
be wired. The maximum wire length between BS (fed
locally) and IC-CU2 or IC-LU is only data limited and
may reach up to 1900 meters.
The board offers the following connections:
•
the Cordless System Manager (on a PC)
•
a printer to log errors
•
4 Base Stations
•
the Feature Enabling Control Unit (FECU).
6.1.3
Feature Enabling Control Unit (FECU)
This plug determines which maximum number of port-
ables are allowed to be connected to the system. This
plug is available for various numbers of cordless tele-
phones. For up to 8 portables no plug is required.
6.1.4
IC-Line Unit (IC-LU)
The IC-LU is the line board controlling up to 8 Base
Stations (BS). This board transcodes the voice signal
(PCM <-> ADPCM) for 8 simultaneous speech chan-
nels in the Speech Processing Unit (SPU), provides
echo cancelling, controls the digital link and power
feeding. The wiring distance with remote power feed-
ing to the BSs using only the serial communication
wires SC0 and SC1 is limited to 400m.
For line lengths up to 1600m additional Express Power
