20 Overview of IP T runk 3.01 In addition to routing IP T elephony calls with locally configured call-routing options, IP T r unk 3.01 takes advantage of the centr alized IP T elephony call routing of an H.323 Gatekeeper residing on a Signaling Ser v er elsewhere on the network. The H.323 Gatekeeper allows or denies access to IP network gatew ays.[...]

Introduction 21 • handles the call based on the retur n message from the Gatek eeper IP T runk 3.01 (and later) accesses additional devices through the Gatekeeper . It is no longer necessar y to individually provision the entire mesh at each IP T r unk 3.01 (and later) node. Instead, the calls go to the Gatekeeper , which provides the IP T runk 3[...]

22 Overview of IP T r unk 3.01 W ARNING The only Gatek eeper that IP T runk 3.01 (and later) officially suppor ts is the CS 1000M Gatekeeper . Gatekeeper calls made between the CS 1000M system and IP T runk 3.01 (and later) are directly-routed calls. Directly-r outed calls In directly-routed calls, the Gatekeeper returns the IP address of the call[...]

Star tup and registration 23 Figure 3 "Gatekeeper-routed call" (page 23) represents a Gatekeeper-routed call. The destination IP address provided b y the Gatek eeper is the Gatekeeper’s IP address. All messages are routed through the Gatekeeper . Figure 3 Gatekeeper-routed call Startup and registration On system star tup , the IP T runk[...]

24 Overview of IP T r unk 3.01 The flag value is ignored when the provisioned Gatek eeper is a CS 1000M Gatekeeper . On star tup, if the IP T runk 3.01 (and later) Leader is provisioned to use a Gatekeeper , it seeks out and locates the Gatekeeper using RAS signalling and then registers with the Gatek eeper using an RRQ. As par t of the registrati[...]

IP T runk 3.01 (and later) and CS 1000S/CS 1000M 25 CS 1000M do not require a Gatek eeper Request from IP T r unk 3.01 (and later); therefore , no Request or Confir m is sent. 2. Gatekeeper Confirm (GCF) – F rom the Gatek eeper to the Active Leader , with the functional Gatekeeper IP address. This address is used f or all call control messaging[...]

26 Overview of IP T r unk 3.01 H.323 RAS, IP T r unk 3.01 (and later) uses RAS Messaging to register with the Gatekeeper if provisioned to do so . IP T r unk 3.01 (and later) then processes calls by scanning its Director y Number (DN) information. If the call is not resolved using the local Address T ranslation Protocol Module (A TPM) and IP T r un[...]

IP tr unk card description 41 Backup Leader The Backup Leader card steps in when the Leader is out-of-ser vice. This minimizes service interr uptions. D-channel IP gatewa y The ITG-P entium 24-por t or Media Card 32-por t trunk card with D-channel IP gatew ay (DCHIP) functionality (DCHIP card) is connected by the RS-422 cable to the Multi-pur pose [...]

42 System description (and later) D-channel only controls IP trunk cards in the same IP T runk 3.01 (and later) node. TM 3.1 administration relates the cards with trunks to the DCHIP IP trunk card. The IP tr unk card uses ISDN messages for call control and communicates with the Meridian 1/CS 1000M through the PC Card, using the RS-422 link. On the [...]

IP tr unk card description 43 Card combinations The Leader and DCHIP , or Follo wer and DCHIP , functions can reside on a single IP trunk card or multiple IP tr unk cards. If a F ollower card is equipped with a DCH PC card, it can function as a DCHIP trunk card. As an IP T runk 3.01 (and later) node becomes larger with more trunk traffic, load bal[...]

44 System description Each customer requires one or more dedicated IP T runk 3.01 (and later) nodes. T runks on the same IP T r unk 3.01 (and later) node share the same dialing plan and IP network connectivity . IP T r unk 3.01 (and later) trunks cannot be shared between customers that hav e independent numbering plans and IP networks. It is possib[...]

IP tr unk card description 45 Active Leader and Backup Leader interaction When a Leader card reboots into service, it sends bootp requests to check whether an Active Leader card is present. If it receives a bootp response, this indicates the presence of an Active Leader card and the rebooting Leader becomes the Backup Leader . If it does not receiv[...]

46 System description When a DCHIP tr unk card f ailure occurs, the associated tr unks’ states appear b usy to the Mer idian 1/CS 1000M, so the trunks will not be used f or calls. This b locks the nor mal software action of rev er ting to analog signaling when an ISL DCH f ails. If either end’s DCHIP or DCH connection f ails, ISDN protocol f ea[...]
