Transmit Number of Channels in a TDM Frame
23–16
Specifies the total number of channels that are transmitted in
the TDM modules. One TDM frame contains 2–256
channels.
Notes: 1.
The number of active data links is specified in the RTSAL
field. Table 19-16 describes the TNCF valid value as a
function of the TDMxGIR[RTSAL] field (Receive and
Transmit Sharing and Active Links). For details, see Section
19.2.5.

Table 19-15. TDMxTFP Bit Descriptions
Description
TNCF[8–15] = (number of channels that
transmit on one active link) × (number of active
data links) – 1. the number of active data links
is specified in the RTSAL field.
2.
If TCDBL field is cleared, the minimum number
of channels is limit. The minimum transmit
number of channels is 128 / (transmit channel
size) + 2. for example if the transmit channel
size is 16 bits then the transmit TDM frame
should contain at least 10 channels.
