Time Slot Select. For unframed E1 service (Clear Channel) go to the “Line Option” parameter and select
“Clear Channel E1 (G.703).” For a full framed E1 enter 1-31, for partially filled E1 enter the range of timeslots
using the format for example: 1,2,3,5; or 1-5,10-31. Any entry for timeslots above 31 will return and invalid
selection message.
Line Options: Choose from Clear Channel E1(G.703) or Channelized E1(G.703/G.704). Consult with your
service provider which option is required.
Line Code: Choose from AMI or HDB3. Most E1 applications use HDB3.
Line Build Out: Select 120 Ohms if the E1 connection is made via the RJ-48C connector, select 75 Ohm if
the E1 connection is made via the dual BNC connectors.
FDL Mode: FDL is a T1 application, therefore select ‘Fdl- none’ for E1 applications.
Clocking Mode: Options are Internal or Receive Recover Clock (network). In most applications clocking for
the 2603 will be derived from the E1 network, set the unit for Receive Recover unless instructed otherwise by
your service provider.
Idle code: Options are Enabled or Disabled. When idle code is Enabled, the 2603 inserts idle codes (7E hex)
on unused timeslots. Set this option to Disabled unless instructed otherwise.
Power Down: Options are Normal and Powerdown. When powered down, the E1 will put high impedance
on the input and output lines to protect the device—set unit to Normal for regular operation.
Once all options have been selected, click on the Configure and Activate button at the bottom of the screen.
Additionally, save the configuration by going to the System Configuration > Save menu.
