 Step 1: Click on to edit digital ports. Please see configuration parameters in the tables below.
 Step 2: Click on to edit group. This assigns channels to be used for the digital port. For E1, 30 B
channels can be assigned to the default group; for T1/J1, 23 B channels can be assigned to the default
group.
 Step 3: If fewer than 30 B channels for E1 or 23 B channels for T1/J1 are assigned in default group,
users can click on to add more groups. This is not necessary in most cases and only default
group is needed.
Note:
Currently, the group configuration in digital trunks settings manages outbound routes only. It does not
control inbound routes. Therefore, if the users have configured multiple groups for the digital trunk, please
make sure the inbound routes for those groups have the same inbound rule configured. Otherwise, inbound
call using the digital trunk might not work properly.
The UCM6510 currently supports E1, T1 and J1 digital hardware type. When different signaling is selected
for E1, T1 or J1, the settings in basic options and advanced options will be different. The following tables
list all the settings to configure digital ports when selecting each signaling.
Table 51: Digital Hardware Configuration Parameters: E1 – PRI_NET/PRI_CPE
Basic Settings
Clock
All E1/T1/J1 spans generate a clock signal on their transmit side. The
parameter determines whether the clock signal from the far end of the
E1/T1/J1 is used as the master source of clock timing. If the far end is used
as the master, the PBX system clock will synchronize to it.
 Master: The port will never be used as a source of timing. This is
appropriate when you know the far end should always be a slave to
you.
 Slave: The equipment at the far end of the E1/T1/J1 link is the preferred
source of the master clock.
LBO
The line build-out (LBO) is the distance between the operators and the PBX.
Please use the default value 0Db unless the distance is long.
RX Gain
Configure the RX gain for the receiving channel of digital port. The valid
range is from -24Db to +12Db.
TX Gain
Configure the TX Gain for the transmitting channel of digital port. The valid
range is -24Db to +12Db.
Codec
Select alaw or ulaw. If set to default, alaw will be used for E1.
