General
It is necessary to have a connection to the PSTN or PLMN from the PBX.
The signalling schemes that are supported are the following:
•
ISDN/QSIG using a TLU76/11 or TLU77/1 board or MGU
•
H.323 (trunk) using a IPLU board or an MGU/EMG
•
DASS/DPNSS using a TLU 76/12 or TLU 77/2 board
•
DT/DTMF/R2-MFC using a TLU 76/13 or TLU77/3 board
•
SS7 using a TLU 76/14 board
•
SIP (trunk) using an MGU/EMG or IPLU board
The ISDN/QSIG or H.323 scenario is shown below, see 1 ISDN or H.323
Scenario on page 5 .

PREREQUISITES
4
Prerequisites
Verify with the command license_status that the MX-ONE system has a
valid license for remote extensions. The status printout should be
MOBILE-EXTENSION, which is the license that is valid for both mobile
and fixed remote extension.
If a license is missing or needs to be upgraded, contact the purchase
office where the MX-ONE system was bought. When a new license file
is received, see operational directions for ADMINISTRATOR USER’S
GUIDE section LICENSE HANDLING.
Prepare exchange data for the remote extension in accordance with the
operational directions for MOBILE AND FIXED REMOTE EXTENSION,

Traffic call rate for remote extension
(Erlang)
Note: *) For typical dimensioning the 0.2 Erlang value is used.
Example 1:
For 200 mobile and fixed remote extensions with 0.2 Erlang traffic, the
nearest value in the table is 240. This gives two SPU4 boards and two
TLU76 boards (30+30=60 trunk lines) or two TLU77 boards (23+23=46
trunk lines).
Example 2:
For 5,000 mobile and fixed remote extensions with 0.25 Erlang traffic, 25
SPU4 boards and 750 trunk lines should be needed for the first 2,900
mobile and fixed remote extensions (according to the previous dimensioning table). For the remaining 2,100 remote extensions, 19 SPU4
boards are needed.
In total, 25+19=44 SPU4 and TLU76 or TLU77 (with 1530 or 1173 trunk
lines) are needed for 5000 remote extensions.

Space Requirements
The remote extension feature requires an increased number of
DTMF-tone receivers, since it has the possibility to activate features like
Inquiry, Alternation and Conference. To be able to detect the DTMF
tones, a key code receiver has to be connected during speech state to
receive orders from the mobile extension or fixed remote extension.
If MGU is used, no SPU4s are needed, but additional SPU4s can be
used, for example for capacity reasons, and will then be selected before
the MGU key code receiver resources.
The hardware for DTMF-tone receivers in Media Gateway Classic with
LSU-E is one or more SPU4 boards. Each board uses a board position
and occupies 32 time slots. The boards should be placed in the slots
ending with zero (for example 00,10,20,...) and are located under the
ESD-protection cover.

Mounting
7.1
Mounting the SPU4
The SPU4 boards are to be placed in free device board positions under
the ESD cover. An SPU4 board supplies 32 key code receivers and a
maximum of 32 SPU4 boards can be installed in a LIM.
While carrying out service on the system it is recommended that Electrostatic Discharge (ESD) wristbands are used. For more information about
using ESD wristbands, see installation instructions for INSTALLING
MX-ONE.
For additional information about safety, see the description for SAFETY.
Note: At least one SPU4-board is needed in each Media Gateway
Classic with LSU-E (in a multi gateway scenario), that has an
incoming trunk. If MGU is used, no SPU4s are needed.
The following is required:
•
SPU4 boards must be placed in all Media Gateway Classic with
LSU-E, where trunk lines are installed.
•
The HLR for a remote extension should be initiated in the LIM
where trunk lines are installed in order to avoid extra inter-LIM
signaling.
For information about how to install boards in the magazine, see installation instructions for INSTALLING MX-ONE.
7.2
Power Equipment
No external power supply is needed for the SPU4 boards.

Post Installation Measures
Any doors or other mechanical parts that have been removed should be
replaced in their original positions.
SPU4 has several on-board LEDs, both for normal operation (four LEDs
placed close to the board front) and debugging purposes (placed internally on the board), 2 SPU4 LEDs when the Board is in Normal Operation on page 12 .
Figure 2: SPU4 LEDs when the Board is in Normal Operation
LEDs can be checked to see if the board is in normal operation (see the
above figure):
12
•
The four LEDs placed close to the front of the board shows the
status of the Ethernet interface. (the DTMF32 application does not
use this interface).
•
The internal LEDs (L5 and L6) glow intermittently as an indication
that the device processors and Digital Signal Processors (DSPs)
are working properly.
