Nortel Networks NN43001-563 IP Trunk 3.01 (and later) requirements

IP Trunk3.01 (and later) requirements 27

There are no direct media paths between the Meridian 1 telephones and the

CS 1000M telephones. There are direct paths between the IP Trunk 3.01

(and later) IP trunk cards and the CS 1000M telephones.

When the IP Trunk card is in a CS 1000 system, it can take advantage

of the Dynamic Loss Plan developed for the IP Peerproduct. This allows

the system core to inform the IP Trunkcard of the correct pad levelsto be

used. As with IP Peer, it also allows the creation of a custom table when the

environment requires one.

When using Dynamic Loss Plan, the node must be provisioned to have a

default loss plan pad of 0 in both the transmit and receive directions. This

allows a 0 transmit and receive levelwhen the IP Trunkhas a tandem to

another trunk device, improving voice quality.

A CS 1000M network is generally designed for use with a G.711 Codec.

In cases where minimizing bandwidth usage in a CS 1000M network is a

consideration, G.729 might be used.

Recommendation

Nortel recommends provisioning G.711 Codec in IP Trunk 3.01 (and later) and in

all other network equipment to facilitate communication with CS 1000M.

IP Trunk 3.01 (and later) requirements

IP Trunk3.01 requires a minimum of Release 25.15 software. Tointerwork

with the CS 1000M Gatekeeper, CS 1000 Release 3.0 software (or later)

is required.

Table1 "IP Trunk 3.01 (and later) package requirements" (page 28) lists the

package requirements for the IP Trunk3.01 (and later) application.

Unlike ITG Trunk2.0, Q-Signaling protocol (QSIG) suppor t is not required in

IP Trunk3.01 (and later), though it is available for Large Systems. Meridian

1 Option 11C Cabinet, CS 1000M Cabinet, Meridian 1 PBX 11C Chassis,

and CS 1000M Chassis do not support QSIG signaling. Therefore,the

Multi-purpose Serial Data Link (MSDL), applicable only to Large Systems,

is recommended but not mandatory; the earlier D-channel interface cards

can provide Meridian Customer Deﬁned Network (MCDN) ISDN Signaling

Link (ISL). QSIG and MSDL are incompatible for featuretranspor t. If both

QSIG and MSDL are conﬁgured on the network, this can cause the loss of

features such as Name Display,Ring Again, and Transfer Notiﬁcation and

subsequent path simpliﬁcation operations.
