Block on page 548
Table 614. DS1/E1 Signal Connectivity Matrix
Note: See
Each box represents a set of 28 or more output bundles from the cross connect (XC) block. A bundle consists of
three standard data path signals [normally DATA, CLK, and FS or STFREQ], plus, in many cases, AUTOAIS, and,
in some cases, RAI or PTRADJ signals.
22.5.2 DS1/E1 Register Definition
For every valid output signal (bundle) from the cross connect, one input signal (bundle) to the cross connect is
steered to the destination, first via a block select (one of 8) and then via a channel select (one of 28, except exter-
nal I/O, which is one of 29). Therefore, each box in
ister map.
Note: By specifying on a per-output basis, collisions are avoided and broadcast/multicast options are preserved
The crosspoint’s connectivity is determined by a set of source identifiers (SOURCE_IDs), one for each channel
leaving the crosspoint switch. A DS1/E1 (XC1) SOURCE_ID is therefore defined as follows:
The SOURCE_BLOCK[2:0] is defined as:
The CHANNEL_ID typically ranges from 1 to 28 (29 for EXT). Values 0, 30, and 31 (and usually 29 as well) are
unused.

(that is, multiple outputs may share the same source identifier). For E1 signals, only 3 out of 4 channels are
used (channel numbers that are even multiples of four are typically disallowed).
