22.3. Routing Matrices Explained
At the heart of
T
ieline codecs is a digital routing switcher. It enables the codec to
be configured for a whole range of possible broadcast applications, particularly
where different configurations for inputs, outputs and monitoring are required. It
also enables the user to configure for POTS, ISDN, GSM, 3G, X.21, satellite
ISDN, IP/Internet, single channel or dual channel operation. There may also be
a requirement for communications as well. The router can even configure full
talkback operation between a studio producer and the remote broadcast codec.
Each codec profile contains 10 programmable routing matrices (as displayed in
the Matrix Map menu), that enable the user to program audio routing for normal
program, cue functions, remote cue, phone cue, local talkback and remote
talkback. Two separate ‘Global’ matrices for muting program and monitoring are
also provided but are not included in the profile.

field unit routing matrices have six inputs - four are hard-
wired and two are virtual. Of the four wired inputs, two are balanced mic/line
inputs, one is a phone input (used for monitoring dial tones when dialing and for
use as a phone input via a POTS module) and there is an auxiliary input. The two
virtual inputs are for the two decoder channels.
There are 12 outputs in the router of which 8 are wired and 4 are virtual outputs.
Of the 8 wired outputs, 2 are balanced outputs, 4 are for headphone monitoring,
one is for a phone connection (via a POTS module) and one is for the Aux
(auxiliary) output. Of the 4 virtual outputs, 2 are for the
Encoders
and 2 are for
the PPM meters.

A set of reference matrices is provided with the

user to have a starting point for setting up the codec. Other matrices can be
created and amended by the
