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>

Step	Command	Purpose
1	[name] (hw-type)[slot/port]# [no]	Enable/Disable the PRI port.
	shutdown	Default: shutdown (which is disabled)

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>

Step	Command	Purpose
1	[name] (prt-e1t1)[slot/port]# port-type	Changes operation mode of the port.
	{e1 t1}	Restriction: Only available for e1t1 ports
		Default: e1

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>

Step Command Purpose

1[name] (prt-e1t1)[slot/port]# clock {auto Configures the clock-mode of the port.

master slave} Default: master

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.
