5.2 EXN104 Basic Parameters

5.2.1 Default Settings

Under normal conditions, the FE-E1 Converter is managed from PEM.

The FE-E1 converter has the following set of default data stored in FLASH

that can only be changed using the Local Craft Tool:

• E1 line coding, default = HDB3.

• E1 lines in use (1 to 4), default = 4.

• E1 framing type (BFA or CRC4), default = CRC4.

• Synchronization (Clock master or slave), default = clock master.

• Management VLAN ID (1 to 4095), default = 246.

These default values are commonly used for E1 transmission, and should

bring the E1 link into service in most networks. The FE-E1 converter

(EXN104) automatically selects the synchronization mode, which means

that the converter at the Central Office will run as master and the converter

at the Remote site will runs as slave. If the converter does not know if it is

placed at the Central Office or the Remote site, it will run as master.

The converter can be forced to run as master or slave through PEM.

When the converter is in service it can be configured through PEM but E1

lines in use can only be changed by using the Local Craft Tool. Please refer

to the Local Craft Tool User’s Guide for detailed information about how to

use it.

5.2.2 T1 Transmission Parameters

The EXN104’s default setup is to run in E1 mode, which means that in

order to make it run in T1 mode it must be configured before connecting it

to the network. The SNMP MIB parameters are changed by using the Local

Craft Tool (LCT) and for a detailed description of how to use the LCT

please see the Local Craft Tool User’s Guide. Furthermore, the remote site

must be configured first and then the site at the Central Office.
