ISDN-PRI "D" Channel Supported on TN767E Card in Definity G3si v11 Switch?

[SoHandle]

Does anyone know if the TN767E card supports ISDN-PRI with "D" Channel?
I was told by an Avaya Partner firm that it supports ISDN-PRI but not the "D" channel unless I get the TN464 card.
However, I was told by Avaya Remote Support Engineer that it does support ISDN-PRI with "D" Channel.
So, who do i believe?

tn767E supports d-channel isdn in g3si and g3csi but not in g3r

These packs can work with x.25 communication links and processor channels in loads that
do not have tn778 packet control prior to g3v7 where the pkt bus is added with tn794 and
all x.25 isdn must be removed prior to upgrade. tn794 net/pkt may or may not need tn2400
for g3v7 and g3v8 depending on the control carrier. When upgrading to g3v9 or higher for
g3si the tn2401 net/pkt replaces the tn794 and provides pkt-bus.

bsh,
Thanks for the clarificatiom.

bsh,

I was told the following by a tech but it sound like he is not sure himself.
Does this make sense:
• The customer may require a processor interface card
<This appears to be present as a TN765, but the TN794 is required to provide D-channel support in the G3Si later than V6.
01A PROCESSOR TN2404 000003
01A PROCR INTERFACE 1 TN765 000020
01A NETCON/PKTINT TN2401 000004
01A TONE/CLOCK TN2182C 000002
G3Si V8 and later software uses the Packet Control function of the TN794 Netcon/Pkt Interface circuit pack to run the D-channels, rather than using a link on the TN765 Processor Interface circuit pack as introduced in V6. We will need to propose a TN794 to the customer.
The TN794/TN2400 Sandwich Board Assembly (com code 848254942) is required for certain G3Si carriers based on the vintage of the backplane.
The sandwich board bridges the packet bus to the TN794 Netcon/Pkt Interface circuit pack.
The TN794/TN2400 Sandwich Board Assembly cannot be separated into two circuit packs.
The following processor carriers require only theTN794 circuit pack; the TN794/TN2400 sandwich pack is not required:
J58890L-2 List 25 or List 31;
J58890M-2 List 15; J58890AH-2 List 13; or
J58890AJ-2 List 12
All earlier carriers require the TN794/TN2400 sandwich circuit pack assembly.

tn2404 supports g3siv9, v10, v11, v12 and must use tn2401 net/pkt board
isdn is only supported over packet bus and will work without tn765.
v7 and above software will not work with tn765 processor interface that converts x.25 to isdn.
x.25 with a tn765 will work for audix, cms, dcs, etc. (just won't work with x.25 isdn processor channels as in v6 and earlier Definity loads)

Then net/pkt tn2401 may or may not need a piggyback tn2400 which is carrier dependant.
