00
Types of AIS Pattern Generation Select
These bits permit the user to do the following.
a. To select the type of AIS Pattern that the Transmit E1 Framer block will
transmit.
b. To force (via Software-control) the transmission of the “selected” AIS
Pattern.
N
OTE
:
For “normal” operation, the user should set these bits to “[0, 0]”.

AIS Defect Declaration Criteria[1:0]:
These bits permit the user to specify the types of AIS Patterns that the
Receive E1 Framer block must detect before it will declare the AIS defect
condition.
N
OTE
:
In revision C of XRT86VL32, Receive E1 framer will always monitor
AIS16 condition and report the state and interrupt status without
having to enable these two bits. AIS16 alarm state and interrupt
status can be read from register 0xnB12, 0xnB13.

Transmission of AIS Indicator is Disabled
The Transmit E1 Framer block will transmit “nor-
mal” E1 traffic to the remote terminal equipment.
01
Unframed AIS alarm
Transmit E1 Framer block will transmit an
Unframed All Ones Pattern, as an AIS Pattern.
10
The AIS-16 Pattern
In this case, Time-slot 16 (within each outbound
E1 frame) will be set to an “All Ones” Pattern.
11
Framed AIS alarm
Transmit E1 Framer block will transmit a Framed
All Ones Pattern, as an AIS Pattern.

AIS Defect Declaration Criteria
00
AIS Defect Condition will NOT be declared.
01
Receive E1 Framer block will detect both
Unframed and Framed AIS pattern
10
Receive E1 Framer block will detect AIS16 (Time
Slot 16 AIS) pattern*.
11
Receive E1 Framer block will detect only Framed
AIS pattern
