Configure IP Trunk 3.01 (and later) data in TM 3.1

241

Select the Card Density from the drop-down list: 24 ports for an
ITG-P 24-port card; 32 ports for the Media Card.

Enter the ISL D-channel logical device number. The range is 0 –
255 for Large Systems; 0 – 79 for Small Systems.

If the card will be a DCHIP card, select the DCHIP is on this Card
check box. The DCHIP card must have an NTWE07AA DCHIP
PC Card with an NTCW84EA Pigtail cable installed and must be
connected to the ISL DCH port on the MSDL or SDI/DCH card.

The standard configuration is to put the first DCHIP PC Card on
Leader 1 and additional DCHIP PC cards on Follower cards.

Select a Protocol for the DCHIP card from the drop-down list. The
protocol selected must match the protocol configured in LD 16 in
the Route Data Block at the IFC prompt with respect to SL1, or
ESGF/ISGF QSIG interface (IFC), and in LD 17 at the IFC prompt
under ADAN DCH.

In LD 16, if SIGO is set to STD, select the SL1 protocol. If SIGO
is set to ESN5, select SL1 ESN5 protocol. In a mixed ESN5 and
non-ESN5 network, configure an ESN5 prefix for the non-ESN5 IP
telephony gateways by using the

esn5PrefixSet

command from

the ITG shell CLI.

"Change default ESN5 prefix for non-ESN5 IP

telephony gateways" (page 270)

The choices are SL1, SL1 ESN5, ESIG and ISIG for networks
consisting of Large Systems. For networks that include Small
Systems, the choices are SL1 or SL1 ESN5.
In addition to IP Trunk 3.01 (and later) nodes, the IP telephony
trunk network might also contain ITG Trunk 1.0 Basic Trunk
nodes or Nortel IP Telephony Connection Manager. Use H.323
V2 node capability for these nodes.
Once a DCHIP for the IP Trunk 3.01 (and later) node is defined,
the protocol field is greyed out when other cards in the same IP
Trunk 3.01 (and later) node are selected.

The QSIG checkbox enables IP Trunk 3.01 to be configured with a
QSIG channel address length of 7 bits for Primary Rate D-Channels
or 8 bits for an ISL D-Channel used in prior releases of IP Trunk
software. The QSIG checkbox is checked or unchecked by default,
depending on the software release running on the system. The
checkbox is enabled only when the selected protocol is QSIG (ESGF
or ISGF) and the node version is IP Trunk 3.01.

Enter the First CHID (Channel ID) for this IP trunk card in the First
CHID edit box. The First CHID range is:

•

1 – 382 for the NT0961AA ITG-Pentium 24-port trunk card
