E&M Card
HYBRID
Available for the two-wire 8108 E&M card only, the Hybrid option assigns a three byte pattern
to define the adjustment for return loss (similar to Build Out Capacitors). The default, set1,
balances to the ideal termination of 600
Ω
@ 2.15mF. The other settings are reserved for future
use.
SIG CONV
The Signaling Conversion parameter allows you to change the transmit ABCD signaling bits
from ITU (E1) to ANSI (T1) standards. This conversion is completed regardless of the
associated type of WAN (CSU/DSX or CEPT).
Select off if ANSI signaling is used, or select on to convert the transmit signaling from ANSI
to ITU according to the Interface Card Conversion Table for E&M signaling. This setting also
converts the receive signaling from ITU to ANSI format.
RATE
The Rate parameter allows you to use the voice compression capabilities of an ADPCM card.
If that card is not present in the system, the Rate is set to 64k and cannot be changed. The 64k
setting (default) is the normal encoding/decoding rate for voice circuits.
ADPCM voice channels are assigned in pairs by designating two voice ports (E&M, FXO or
FXS) to the same WAN link and time slot, and then selecting rate settings for the pair that add
up to 64 kbps. The following pairing combinations are possible:
24K,1+40K,2 (24 kb coding on one side of the time slot and 40 kb coding on the other side of
the same time slot)
32K,1+32K,2 (32 kb encoding on each side of a time slot)
40K,1+24K,2 (40 kb coding on one side of the time slot and 24 kb coding on the other side)
Number 1 after the rate setting assigns that portion of the voice port pair to the odd side of the
ADPCM pair. Number 2 after the rate setting assigns that portion of the voice port pair to the
even side of the ADPCM pair.
For more information about voice port assignments to a time slot and ADPCM card.
ADPCM
The ADPCM parameter lets you assign the current port to an ADPCM card in the system. The
default setting is n/a and only changes when a Rate smaller than 64k is selected (see above).
You can then select which ADPCM card to use for the port (this assignment is made by chassis
slot number). The options are slots P1, P2, and P3.
