Page 44: Isdn Signaling Link
A dedicated point-to-point signaling link is established between the two Meridian 1 systems. The signaling information for the selected analog trunks is transported over the ISDN signaling link. The analog ISL TIE trunks are for user voice transport. If the D-channel link is down, call control returns to normal in-band analog trunk signaling.
Page 45 ISDN signaling between the Meridian 1 and the ITG ISL Trunk supports the delivery of Calling Line Identification (CLID) and feature messaging. ISL DCH signaling provides the necessary signaling connection over which data, including CLID and feature-specific messaging, can be passed. ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...
Page 46 Page 46 of 378 Description On large systems, the DCH interface to the Meridian 1 uses the MCDN or QSIG GF protocols and their variants to transmit call and feature control messages to the DCHIP card. Small systems use only MCDN because the NTAK02BB SDI/DCH card does not support QSIG protocols for ISL.

Page 49: Dialing Plans
It is desirable to distribute calls to multiple nodes at a remote destination Meridian 1. The configuration of multiple dialing plan entries at the local ITG node allows routing based on the dialed digits. ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...
Page 50: North American Dialing Plan
Page 50 of 378 Description For example, Meridian 1 switch B node B1 has two entries for NPA 408 and 4085 which point to nodes A1 and A2 of Meridian 1 switch A, respectively. Calls from B1 with dialed digits 408-5xx-xxxx are routed to the ITG node A1 while all other 408-xxx-xxxx calls are routed to ITG node A2.
Page 51: Flexible Numbering Plan
ITG Trunk 2.0 supports ESN5 Network Signaling protocol only, in addition to standard (i.e., non-network) signaling. ITG 2.0 supports a mixed network consisting of ESN5 and standard network signaling nodes. ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...
Page 52: Echo Cancellation
Page 52 of 378 Description Echo cancellation All telephony voice services now in use reflect some level of echo back to the user. The term “echo” refers to the return of a signal’s reflection to the originator. Packet voice networks introduce sufficient latency to cause what a caller would consider an audible echo.
Page 53: Quality Of Service
Note: QoS is measured per remote gateway. For example, if a given Leader has three remote leaders in its dialing plan table, it will perform three QoS measurements and calculations (one per remote gateway). ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...
Page 54: Quality Of Service Parameters
Page 54 of 378 Description Since IP trunks use the same port for both voice and fax, the same QoS thresholds apply for both voice and fax calls. Network requirements for fax are more stringent than for voice. Fax protocols, such as T.30, are more sensitive to transmission errors than the human ear.

“time exceeded” message, and so on, until all hops have been identified. The traceroute IP datagram has a Port number unlikely to be in use at the destination (usually >30,000). This causes the destination to return a ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...
Page 56: E-Model
Page 56 of 378 Description “port unreachable” ICMP packet which identifies the destination host. Traceroute can be used to measure round-trip times to all hops along a route, identifying bottlenecks in the network. E-Model The ITG uses the E-Model, a method similar to the ITU-T Recommendation G.107, to determine voice quality.
Page 57: Fallback To Alternate Facilities
Stepback on Congestion allows a new route to be found for the call (for instance, the PSTN). The route selected depends on the customer’s database. If an alternate ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...

There is a default gateway entry (0.0.0.0) that specifies the gateway address for this traffic. The ToS ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...
Page 60 Page 60 of 378 Description does not matter for this route. If the route and ToS do not match any of the other route entries, the packet is routed here. The entry is configured for the T-LAN interface. Local subnet packets is the H.323 call data intended for another ITG node connected to the same subnet.
Page 61: Fax Support
Signaling specified by H.323 V.2 protocol is used for ITG to ITG call setup. Modules supporting facsimile transmission are responsible for the following: • fax speed detection and adjustment • protocol conversion from G3 Fax to RTP payload for fax data transfer ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...
Page 62: Remote Access
Remote Access Remote Access is supported on the ITG. Remote Access allows a MAT user with no ITG data, including Nortel Networks support personnel, to manage the ITG ISL Trunk card remotely. Management and support of the ITG network depend on IP networking protocols including SNMP, FTP, and Telnet.

Page 108 of 378 ITG Engineering Guidelines QoS Evaluation Process Overview There are two main objectives when dealing with the QoS issue in an ITG network: (1) to predict the expected QoS, (2) to evaluate the QoS after integrating ITG traffic into the intranet. The process for either case is similar, one is without ITG traffic and one is with.

Page 120 Page 120 of 378 ITG Engineering Guidelines Serialization delay This is the time it takes to transmit the voice packet one bit at a time over a WAN link. The serialization delay depends on the voice packet size and the link bandwidth, and is given by the following formula: Serialization delay in ms = 8*(IP packet size in bytes)/(link bandwidth in kbit/s)
Page 121 As can be seen in Figure 18, queueing delays can be significant for links with bandwidth under 512 kbit/s, whereas with higher speed links they can tolerate much higher utilization levels. ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...
Page 122: Reduce Link Delay
Page 122 of 378 ITG Engineering Guidelines Routing and hop count Each site pair takes different routes over the intranet. The route taken determines the number and type of delay components that add to end-to-end delay. Sound routing in the network depends on correct network design at many levels, such as the architecture, topology, routing configuration, link and speed.
Page 123 Most of this link's delay is caused by queueing. Looking at Figure 18 on page 121, if you upgrade this link to T1, you can shave about 19 ms off the delay budget. ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation...
