CNV
The Conversion (CNV) parameter allows you to request that PCM companding and signaling
conversion be performed on this cross-connect circuit. Since these conversions only apply to
voice circuits, if the TYPE selected is
d
(data), then the only acceptable value here is
n/a
.
Similarly, if the TYPE selected is
v
(voice without signaling), the system will only allow users
to request PCM companding conversion. If the TYPE is
v&s
(voice with signaling), then users
can select any combination of companding and/or signaling conversion.
If the TYPE is
v
or
v&s
, the system will first ask users to "Select PCM CONV:" for defining
the type of companding conversion users require (see Figure 4-35). The options are no
companding conversion (
none
), convert the incoming
A-mu
(A-law signal to mu-law) and
convert the incoming
mu-A
(mu-law signal to A-law).
If the TYPE is
v&s
, the system will prompt users to "Select SIG CONV:" for selecting the
type of signaling conversion needed (see Figure 4-36). The option
none
(default signaling
conversion) is where a bit pattern of "0000" will automatically be converted to "0001" in the
T1-to-CEPT E1 direction.
