Configuration Options for AS2000 and ConnecT1 Plus

Access Manager 2000 User Manual

Select the framing format used on the network. This can be SF (D4),

ES , or UNFRAMED, as required. The default setting is ES . The far-end

circuit element must use the same framing option.

Note:

If EQP Framing Format is Unframed, then the NET Framing

Format must also be Unframed.

If clear-channel operation is required, enter YES to select B8ZS line

coding.

When selecting B8ZS coding, first be sure

the network is compatible with

B8ZS, which introduces intentional bipolar violations into the transmitted

DS1 signal. Call the telephone company to confirm this. Set this option

identically at both ends of the circuit.

Otherwise enter NO, which will select AMI coding (default setting).

If the equipment uses SF framing and the network uses ESF, select YES

to ensure proper handling of CRC-6 codes toward the network by the

CSU. This is the default setting.

If both the equipment and network use ESF, set this option to NO

(disabled).

If the equipment uses D4 framing and the network uses ESF, select YES

(default setting) to allow the CSU to transcode an SF (D4) yellow alarm

to an ESF yellow alarm on the ESF Data Link.

If both the equipment and network use the same type of framing, select

NO to disable yellow alarm transcoding. When disabled, yellow alarms

are passed through without being transcoded.

Yellow alarm is also known as Remote Alarm Indication Signal (RAIS).

The Signal to EQP on NET Errors option is functionally

similar to the Signal to NET on EQP Errors option previously

described. See warning in that section. The default is YES (signal).
