Patton electronic 2800 user manual Mode port e1t1 slot port, Configuring T1/E1 port-type

OnSite 2800 Series User Manual5 • T1/E1 port configuration

Mode: port e1t1 <slot> <port>

Step	Command	Purpose
1	[name] (prt-e1t1)[slot/port]# [no]	Enable/Disable the T1/E1 port.
	shutdown	Default: shutdown (which is disabled)

Configuring T1/E1 port-type

The T1/E1 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}	Default: e1

Configuring T1/E1 clock-mode

The T1/E1 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.

Mode: port e1t1 <slot> <port>

Step	Command	Purpose
1	[name] (prt-e1t1)[slot/port]# clock {mas-	Configures the clock-mode of the port.
	ter slave}	Default: master

Configuring T1/E1 line-code

Three different line codes can be selected on the T1/E1 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.

Mode: port e1t1 <slot> <port>

Step	Command	Purpose
1	[name] (prt-e1t1)[slot/port]# linecode	Configures the line-code of the port.
	{ami b8zs hdb3}	Default for e1: hdb3
		Default for t1: b8zs
