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
[ name ] (prt-e1t1)[slot/port]# port-type
1
{e1 | t1}
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
[ name ] (prt-e1t1)[slot/port]# clock {mas-
1
ter | slave}
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
[ name ] (prt-e1t1)[slot/port]# linecode
1
{ami | b8zs | hdb3}
Configuring T1/E1 framing
Four framing formats are available for selection on the T1/E1 port. Unframed can only be used if the encapsu-
lation is set for hdlc. All other currently available upper layer (encapsulation) protocols do not run in unframed
mode, but in one of the framed modes.
In structured mode, E1 can be configured for crc4 or non-crc4. T1 has a single framed option, esf.
