RAI (Yellow Alarm): ON = RYEL or RMYEL. This status is ON when there is
frame synchronization to an E1 or T1 frame pattern and the frame’s
remote alarm indication bit is set.
AIS (Blue Alarm): ON = RAIS. This status is ON when there is a valid
encoded signal present, no frame synchronization present, and an all-1’s
data pattern is being received.
FrameMode
Syntax
SETDefault !<path> -PAth FrameMode = T1_SF | T1_ESF | E1_CRC4 |
E1_NOCRC
Default
E1_CRC4
Description
The FrameMode parameter allows you to specify the frame mode.
Before changes to this parameter can take effect a “SETDefault !<path>
-PATH ConnControl=Enable” command needs to be issued on the
corresponding connector.
Values
LineDistance
Syntax
SETDefault !<path> -PAth TILineDistance = LH1|LH2|LH3|LH4|SH1|SH2|
SH3|SH4|SH5|SH7
Default
SH7
Description
The LineDistance parameter determines the supported long haul (LH) or
short haul (SH) line distance. Long haul values are in units of dB and short
haul values are in units of feet. Note that only short haul is supported for
E1 lines.
Before changes to this parameter can take effect a “SETDefault !<path>
-PATH ConnControl=Enable” command needs to be issued on the
corresponding connector.
T1_SF
Superframe format T1.
T1_ESF
Extended Superframe format T1.
E1_CRC4
CRC-active E1.
E1_NOCRC
E1 without an active CRC.
