！DANGER
Do not install or remove a power cable with power on. Transient contact between the
core of the power cable and the conductor might generate electric arc or spark, which
can cause re or damage to the human body. Before installing or removing the power
cable, turn off the power. During the device power-on, do not wear the ESD wrist strap.
This helps prevent electric shock.
CAUTION
Before touching the device, or holding the boards, wear the antistatic gloves or the
antistatic wrist strap to prevent the electrostatic discharge of the human body from
damaging the sensitive components. Ensure that the other end of the antistatic wrist
strap is well grounded. Before installing devices, ensure that the cabinet is effectively
grounded.

1 Preparation
Unpacking Inspection
Check the received materials according to the packing list and ensure that all
the materials specied in the contract arrive at the site. After the inspection, sign
on the packing list with the customer and keep a backup of the packing list.
Preparing Installation Tools
• Cross screwdriver (M3–M6) • Flat-head screwdriver (M3–M6)
• Mount bar • Diagonal pliers
2 Installing the Subrack
Select a narrow brim of the cabinet
mounting bar as the baseline and
use M4 screws to install the guide
rail. The lower edge of the guide rail
must be ush with the baseline.
Install floating nuts in the first
and sixth square holes above the
baseline. (Select the first and third
square holes when installing the
U1911.)
Adjust the mounting ears (folded
by default) at the two sides of the
subrack based on the cabinet status
to prevent the situation that the
cabinet door cannot be closed after
cables are connected.
Put the subrack on the guide rails
and push it into the cabinet. Use
four M6 screws and the oating nuts
on the mounting bar to fasten the
device.

Installing a Board
Loosen the screws on the ller panel
and use the at-head screwdriver to
remove the ller panel.
Adjusting Components on the Board
If you want to use the T1 trunk, you must remove the jumper caps on the CVP
board (U1910&U1930) or MTU board (U1911&U1960&U1981).
Insert the board into the empty slot,
press the ejector lever into place,
and fasten the captive screws.
SD0 SD1
If you want to use the built-in VMS service (U1911&U1960&U1981) or
customize the system announcements, ensure that you have installed an SD
card in slot 0 of the MTU board.

Connect and fasten one end of the E1/T1 trunk cable to the E1/T1 port on the
CVP or MTU board, and connect the other end to the E1/T trunk cable of the
peer device directly or through the distribution frame. Connection rules:
• E1 cable: For the same link number X, connect local TX to peer RX and local
RX to peer TX.
• T1 cable: For the same link number X, connect local RX/TX to peer RX/TX.

Connecting the Network Cables
Connecting the E1/T1 Trunk Cables
Use the PGND cables to connect
the device to the ground bar or
ground point of the grounded
cabinet. A PGND cable must
be as short as possible and
generally cannot exceed 45 cm.
CAUTION
Ensure that the device is effectively connected to the
nearest ground to avoid noises in voice calls.
！
Use network cables to connect the
following ports to the switch:
• CVP: FE1 and FE2
• SCU: GE0 and GE1
The adaptive network ports support both
straight-through and crossover cables. To
ensure sufcient network bandwidth, use
Cat 5e GE network cables.
• If there are active and standby SCU boards (U1981), connect network cables
to both SCU boards.
• On the BTU board (U1911&U1960&U1981), use a straight-through network
cable to connect the BRI S/T port to the peer NT device.
*The E1 trunk cable delivered with the device has BNC connectors assembled.If
the peer end uses SMB connectors, assemble corresponding SMB connectors
by referring to appendix a.

Connect and fasten one end of the high-density user cable to the FXS/FXO
port on the ASI or OSU board, and connect the other end to a POTS phone or
an FXS port of the upper-level ofce directly or through the distribution frame.
The high-density user cable delivered with the device has no RJ11 connector
assembled. See appendix d to assemble an RJ11 connector if you need one.

• The power cables, signal cables,
and PGND cables must be routed
separately. They must be spaced apart
at least 30 mm. Do not bundle or mix
them together.
• Use one cable tie every 200 mm. The
cable strap is clearly cut, the cable ties
point to the same direction, and there
is no exposed thorn.
• Do not lay out cables on the
dissipation holes; otherwise, heat
dissipation of the device and the
service life of cables are affected.
• The cables are arranged straightly
and smoothly. Redundant length is
reserved.

5 Powering on and Checking the Device
Powering On the Device
Connect the device to an external power supply and turn the switch on the panel
of the power module to ON. When the device is powered on, it takes about ve
minutes to start. After the device starts, the fan sound becomes low.
Checking the Indicators
The following table lists the normal status of each indicator. If any exception
occurs, contact technical support engineers.
Indicator Name Color Normal Status
PWR Green On
RUN Green Blinking
ALM Red Off
LOS*Yellow Off
RFA*Yellow Off
* The LOS and RFA indicators on CVP and MTU boards indicate physical
connection status of each E1/T1 trunk. If they are off, the connection is proper.
Otherwise, check the cable connector and the peer device. The CVP board
(U1930) allows two E1/T1 trunks to share the same pair of indicators. The
indicators are off only when the both E1/T1 trunks are connected properly.

AppendixesAssembling the Signal Cable Connectors
Assembling the SMB/BNC Connector (for 75-ohm E1 Cables)
The SMB and BNC connectors are used by 75-ohm un-balanced E1 trunk cables.
Depending on the device model, either of the following E1 trunk cables with a BNC male
connector assembled is delivered with the device. If an SMB connector is required based
on the peer connector, you can cut off the existing BNC connector and reassemble a
corresponding SMB connector.

connector, applicable to
the U1911&U1960&U1981)
4E1 trunk cable (DB26
connector, applicable to
the U1910&U1930)
This section uses a straight SMB female connector as an example to describe how to
assemble the SMB/BNC connector with the coaxial cable.
Cut off the existing connector and strip
off the jacket of the coaxial cable.
L1: 5–6 mm
L2: 7–9 mm
L3: 10–12 mm
Lead the heat shrink tube and crimping
sleeve through the coaxial cable. Unfold the
external conductor of the coaxial cable to a
trumpet shap.
Insert the insulation and internal
conductor into the connector plug
of the coaxial cable. The external
conductor of the coaxial cable partly
wraps the external conductor of the
connector.
Use a welding tool to weld
the internal conductor of
the coaxial cable with the
internal conductor of the
coaxial cable connector.
Push the crimping sleeve toward the
connector. Crimp the external conductor
of the coaxial cable tight. Use a crimping
plier to tighten the crimping sleeve and
coaxial cable connector.

Assembling the RJ48C Connector (for 100-ohm T1 Cables)
The RJ48C connector is used by 100-ohm balanced T1 trunk cables. Depending on the
device model, either of the following T1 trunk cables with a RJ48C connector assembled
is delivered with the device.
If you need to reassemble a RJ48C connector, strip off the jacket of the twisted-pair
cable, sort the core wires according to the pin assignment, insert the sorted core wires
into the RJ48C connector, and use a crimping tool to crimp the connector. If you do not
have a RJ48C connector, use a RJ45 connector instead.
