Tandem Connection Loss Of Lock, Mismatch, Loss Of Multiframe
Alarms Line AIS Enable: A common control bit for both the A and B
Drop bus Tandem Connection Loss of Lock (A/BnTCLL), Tandem Con-
nection Mismatch (A/BnTCTM), and Tandem Connection Loss Of Multi-
frame (A/BLLM) alarms. A 1 enables any of these alarms for the active
bus to generate line AIS provided control bit RnAISE is set to 1.
J2 Alarm Line AIS Enable: A common control for both the A and B
Drop bus J2 alarms. A 1 enables a J2 Loss Of Lock (A/BnJ2LOL) or J2
Trace Mismatch (A/BJ2TIM) alarm for the active bus to generate line AIS
provided control bit RnAISE is set to 1.
Path Label Alarm Line AIS Enable: A common control for both the A
and B Drop bus path signal alarm (A/BnSLER). A 1 enables a path sig-
nal label mismatch alarm for the active bus to generate line AIS provided
control bit RnAISE is set to 1.
Unequipped Line AIS Enable: A common control for both the A and B
Drop bus unequipped path signal alarm (A/BnUNEQ). A 1 enables a
unequipped alarm for the active bus to generate line AIS provided con-
trol bit RnAISE is set to 1.
Not used:
Upstream AIS Alarm Line AIS Enable: A common control for both the
A and B Drop bus upstream AIS alarm (A/BxUAIS). A 1 enables an
upstream AIS alarm for the active bus to generate line AIS provided con-
trol bit RnAISE is set to 1. Where x is equaled to the numbered STS-1 in
the STS-3.
Select E1AIS: Works in conjunction with the HEAISE control bit
described below. The HEAISE bit must be set to 1 in order for this con-
trol bit to function. A 1 enables the TOH E1 byte AIS detection circuit. A 0
enables the TOH H1/H2 byte AIS detection circuit.
A/B H1/H2 or E1 Byte AIS Enable: Works in conjunction with the
SE1AIS control bit described above. Common control for both the A and
B Drop buses. A 1 enables AIS detection in either the SDH/SONET
H1/H2 bytes (control bit SE1AIS is 0), or in the E1 bytes (control bit
SE1AIS is 1). A 0 disables the detection of an upstream AIS state. Note
that the TU/VT pointer tracking state machine AIS detection circuitry
operates independently of H1/H2 or E1 byte AIS detection circuits.
