Configuring the T1 Network

Access Manager 2000 User Manual

This option allows the CSU to convert an SF yellow alarm (all B2 bits =

ZERO) from the network to an ESF yellow alarm (repetitive [11111111

00000000] bit pattern on the ESF Data Link).

If the network uses SF framing and the equipment (EQP) uses ESF

framing, select YES.

If the CSU is used with one or more DIU 2130s, DIU 1130s, and/or DIU

2140s, such as drop-and-insert, choose NO.

Otherwise, set this option to NO (default setting).

If you want the CSU to continue sending the signal from the equipment to

the network, even after detecting the EQP side signal has excessive BER,

set this option to YES.

The default setting is YES.

CAUTION

Setting this option to NO causes an out-of-service condition during

excessive BER. It begins when the BER threshold is exceeded and

lasts as long as the condition persists, with an additional 97 seconds

to 22 minutes (depending on the

BER Threshold

option selected). If

NO is selected, the signal applied is AIS.

This option is similar to the one above for an alarm caused by a Loss of

Frame (LOF) condition on the incoming signal from the network. Also

set this option to YES if the CSU is used with DIUs. The default setting

is YES.
