CAS Multiframe Alignment Declaration Algorithm Select[1:0]
These bits allow the user to select which CAS Multiframe Alignment Decla-
ration algorithm the Receive E1 Framer block will employ, according to the
table below.

For information on the criteria that the Receive E1 Framer block
uses in order to declare the “Loss of CAS Multiframe” defect
condition, please see register description for the Framing Control

01
The “16-Frame” Algorithm
If this alignment algorithm is selected, then the Receive
E1 Framer block will monitor the 16th timeslot of each
incoming E1 frame and will declare CAS Multiframe align-
ment (e.g., clear the Loss of CAS Multiframe” defect) con-
dition; anytime that it detects 15 consecutive E1 frames in
which bits 1 - 4 (of timeslot 16) do not contain the “CAS
Multiframe Alignment” pattern; which is immediately fol-
lowed by an E1 frame that DOES contain the “CAS Multi-
frame Alignment” pattern.
10
The “2-Frame” (ITU-T G.732) Algorithm
If this alignment algorithm is selected, then the Receive
E1 Framer block will monitor the 16th timeslot of each
incoming E1 frame and will declare CAS Multiframe align-
ment (e.g., clear the Loss of CAS Multiframe” defect) con-
dition; anytime that it detects a single E1 frame in which
bits 1 - 4 (of timeslot 16) do not contain the “CAS Multi-
frame Alignment” pattern; which is immediately followed
by an E1 frame that DOES contain the “CAS Multiframe
Alignment” pattern.
