PRI port configuration task list 193

Enable/Disable PRI port
By default, the PRI port is disabled. The following command is used for enabling or disabling it.
Mode: port <hw-type> <slot> <port>
Configuring PRI port-type
An E1T1 Port can either work in T1 or in E1 (G.704) mode. This mode can be changed dynamically as long
as no encapsulation or encapsulation ‘hdlc’ is set. Be aware that changing the port-type also resets the framing
and linecode parameters to the default values of the new port-type. If port-type change is not allowed due to
current configuration, an error message will be issued.
Mode: port e1t1 <slot> <port>
Configuring PRI clock-mode
The PRI Port can either work in clock-master or in clock-slave mode. This setting defines the clock depen-
dency of the internal data processing. In clock-master mode the internal data processing is running on an inde-
pendent clock source. In clock-slave mode the clock source for internal data processing is recovered from the
receive line interface. Be aware that always a port-pair of clock-master and clock-slave are connected together.
In the other case the data transmission will fail due to bit failures. This command has also the option ‘auto’ that
can be used if the application running on the port is also of an asymmetric nature like master/slave, server/cli-
ent or user/net. Normally, the option ‘auto’ is used if the port is setup for ISDN. In this case, the clock mode
will automatically derived from the Q.921 protocol. If the UNI-Side (User-Network Interface) of Q.921 is set
to ‘net’, then clock mode of the port is automatically set to ‘master’ and if Q.921 is configured as ‘user’ it will
be set to ‘slave’.
Mode: port <hw-type> <slot> <port>
Configuring PRI line-code
Three different line codes can be selected on the PRI port whereas only ‘ami’ is standardized for E1 and T1. If
the port is running in E1 mode, ‘hdb3’ is also configurable and in T1 mode ‘b8zs’. If a linecode will be selected
that is not standardized for the current port mode, an error message will be advised.
