Configuring the T1 Network
5-84 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 .
