Mode:
Port bri
Configure PRI Port Parameters (Layer 1)
For the two PRI port types (E1, T1) clocking mode and linecode can be selected. To work with the port a layer
2 protocol must be bound to it. This is done be specifying an encapsulation.
Procedure:
To configure PRI port parameters
Step
Command
Purpose
1
node(prt-bri)[slot/port]#clock auto
or
node(prt-bri)[slot/port]#clock master
or
node(prt-bri)[slot/port]#clock slave
Specify the clock mode (default: auto)
The BRI port can either generate the clocking
for the line, or accept the clock from the line.
The options ‘master’ or ’slave’ determine the
clocking method:
Master: Generates clock
Slave: Accepts clock
If the clock mode is not specified or set to
auto the setting is derived from the next
higher layer. In case of Q921 this is the UNI
side setting.
NET: clock master
UNI: clock slave
It is not possible to enable the port unless the
clock mode is known.
2
node(prt-bri)[slot/port]#[no] power-feed
Enables the application of power on the S-Bus
to provide power to ISDN terminals.
This command applies only only if if the port
is clock master (network side).
It is only available on products with an inter-
nal, configurable ISDN power supply.
The
no
form of the command disables power-
ing the S-Bus to feed the ISDN terminals.
3
node(prt-bri)[slot/port]#q921
Enter Q921 configuration mode.
