In order to enable the EXN104 converter to convert the Fast Ethernet traffic

to T1 lines the SNMP MIB parameters for the EXN104 must be changed as

follows:

1. T1 framing type (D4 or ESF) = ESF

The framing type ESF contains CRC check and is considered the

better of the two formats. Only the line coding B8ZS has been

implemented when running T1. The T1 frame type can be changed “on

the fly”, which means that it is possible to change from EFS to D4 or

vice versa “on-the-fly”. The framing type is set by changing the

dsx1LineType (OID 1.3.6.1.2.1.10.18.6.1.5) in the MIB to either D4 or

ESF. Only one line has to be set, as all the other lines automatically will

change to the new setting.

The framing type is set to ESF by changing the dsx1LineType (OID

1.3.6.1.2.1.10.18.6.1.5) to 2.

The framing type is set to D4 by changing the dsx1LineType (OID

1.3.6.1.2.1.10.18.6.1.5) to 3.

2. Save the new line type by changing the saveCfgToNvm (OID

1.3.6.1.4.1.193.72.600.1.1.12) to 1. This will save the new setting in the

non-volatile memory. Restart the EXN104 to activate the new line type.

The line coding, when running T1, will automatically change to B8ZS,

which is the only coding that has been implemented.

3. The line coding can be verified by reading out the value of the MIB

parameter: dsx1LineCoding (OID 1.3.6.1.2.1.10.18.6.1.6).
