4. USING AN EXISTING DATAKIT NETWORK Another common approach is to use an existing Datakit network for distribution of the LTS DCTU circuits This only works because the Datakit network is connection oriented and has a constant latency Consequently the timing functions of the DT 4xxx LTCN interface are preserved within the Datakit network Typically a SAM is used at either endpoint Consider the following diagram Tail Circuit Distribution Via Datakit BNS DT 6xxx w IP LTCN ANY SAM or DT 4000 Central Office l l e cables DT 4xxx Notes Isochronous operation is supported only by the DT 4xxx A UTM is the preferred BNS trunk in this deployment In the diagram above the mediation occurs at the DT 4xxx interface The BNS network then transports the BX 25 preserving both the format and the timing Isochronous connections must be connected directly to a 4 device since the BNS network and the SAM in particular cannot support that protocol 03 05 04 Datatek Applications Inc 28 Application User s Manual 12 5 WHAT NOT To DO WITH TAIL CIRCUITS As explained in the previous section the distribution of LTS DCTU connections does work with the Datakit BNS network It does so because Datakit BNS is a connection oriented network with constant paths and constant delays Both of these assumptions are not true with an IP based ne
5. A A The diagram above has such configuration 4 series works in conjunction with the DT 6xxx IP LTCN to handle the IP to BX 25 mediation in a manner suitable for the LTS and or DCTU Since the modem circuits are constant latency they can be distributed remotely This option has on going costs of maintaining the tail circuits but is otherwise trouble free 03 05 04 Datatek Applications Inc 26 Application User s Manual 12 3 OPTION 3 USE A MEDIATION DEVICE IN THE CENTRAL OFFICE One of the most common approaches is to distribute the 4 mediation devices to the central offices The DT 4xxx mediation devices support other systems such as SCC connections and E2A telemetry and are shared with IP LTCN usage A diagram of that deployment is as follows IP LTCN Deployment Distributed Mediation N P di IP LTCN Application e Central Office In the above diagram it can be noted that any port may support one or any protocol oeveral operations systems can share a single mediation device and reduce the overall cost of deployment considerably The DT 4xxx mediation device insures the proper timing and presentation of the interface to the LTS and DCTU using local B X 25 or isochronous cabling at the Central Office 03 05 04 Datatek Applications Inc 27 Application User s Manual 12 4 OPTION 4

See the interface section of this document for more details The host protocol suite is fully supported Status information of the LTS connections will be available if the MLT OS host desires 03 05 04 Datatek Applications Inc 9 Application User s Manual 5 REDUNDANCY amp RELIABILITY ISSUES The Loop Test operation requires a very high reliability Each solution provides some form of protection However the IP LTCN is superior in all regards The DCN approach to this type of reliability was in having the ability of multiple A cabinets access an LTS a single cabinet The MLT host would then be attached to two A cabinets If a BX 25 link from the host to the A cabinet would fail test operations would proceed on the alternate connection If an A cabinet would fail the alternate A cabinet would still be attached to the host and could proceed with the test operations However if a B cabinet should fail then all the LTS connections would not be protected An engineer would need to re cable the LTS links to another B cabinet manually The LCN approach to this type of reliability was hinged on the DKAP making the outbound calls to the SAM endpoints on the BNS network Should the DKAP fail then all connections would be torn down A new DKAP would then be brought into service manually The MLT host would then reconfigure the DKAP and establish new calls to the LTS
13. The host interface to the IP LTCN accepts a connection at TCP port between 30 001 and 30020 inclusive Each TCP port has a hunt group of exactly one They are maintained unique to prevent a rogue host from locking out its partner The host interface provides the means by which messages may be sent to an LTS and responses directed to the originating host Spurious messages from an LTS are sent to all connected hosts simultaneously Duplication of spurious messages is prevented by the IP LTCN 11 3 LTS INTERFACE The LTS interface to the IP LTCN accepts a connection at TCP port between 40 001 and 40 768 inclusive Each TCP port has a hunt group of exactly one They are maintained unique to provide an exact mapping to a particular LTS Exactly one 4 e g DT 4000 DT 4180 DT 4216 DT 4232 DT 4280 port may make a connection to 03 05 04 Datatek Applications Inc 23 Application User s Manual TCP port for a particular LTS ID The DT 4xxx provides B cabinet functions for the IP LTCN 03 05 04 Datatek Applications Inc 24 Application User s Manual 12 TAIL CIRCUITS The IP LTCN has several deployment options Many RBOCs will chose to implement a DCN Drop In where the IP LTCN is dropped in place of an existing DCN When this occurs a tail circuit will exist for some period of time This section details the tail circuit deployment Be
