Description
1) Configure local interface
Enter values for the local interface parameters
2) Configure remote interface Enter values for the remote interface parameters
3) LOS Detection
Set to On or Off
4) Redundancy setup
Set to Auto, Manual Primary (Man Pri) or Secondary (Man Sec),
or Off; shows current activity
You can set values for various parameters for both local and remote modems. To configure an
interface, see Tables 12 and 13 and follow these steps: To configure the 2340 functions, follow these
steps:
1. From the Main Menu type 2, "Functional Configuration," and press
2. From the Functional Configuration menu type 1, "to configure local interface," or 2, "to
configure remote interface," and press
3. At each successive prompt, press
select an option or type a number to select values for the parameters, according to the information
in Table 13.
4. To set up LOS Detection or Redundancy, type
3
or
4
and follow the prompts on the screen.
Note: LOS detection differs by application. For a 530 or 422 (with controls) interface, LOS uses
RTS. For a T22, D22, and T88 interface, LOS uses SCTE. For T1/E1, LOS tracks 175
consecutive zeros. TTL/BNC interfaces do not support LOS.
