Table 1-3 shows the TN2305X/TN2306X specifications. Table 1-3.
Review Configuration and Equipment Example A multimode fiber using an optical power budget of 11 dB and a loss of 1 dB/Km with no connectors yields a distance of 11 Km, which is unrealistic. Using a fiber bandwidth of 500MHz-Km and using the ATM OC-3c symbol rate of 77.5 Mb/s (data rate 155 Mb/s) yields a distance of 6.4Km. In this case the distance is limited by the fiber bandwidth.

Determine ATM Switch Suitability Determine ATM Switch Suitability To fully support DEFINITY Server ATM-PNC and provide nonblocking ATM access between all port networks, ATM switches must support at least 400 point-to-multipoint switched virtual connection (SVC) roots or leaves per OC-3/STM-1 interface.
Preparing for Installation and Upgrades 5. If you answer "yes" to transit traffic, the calculator may or may not be able to determine feasibility. If it cannot, the feasibility displays as UNKNOWN. Table 1-4 shows an example of a calculation. Table 1-4.
Determine ATM Switch Suitability UNKNOWN means that special engineering is required for this application because of the transit traffic. The special treatment is necessary because the feasibility depends on the volume of the transit traffic. Making any of the changes suggested for NO above might make it feasible regardless of the transit traffic. BANDWIDTH LIMITED means that the aggregate trunk bandwidth is insufficient to support the theoretical maximum demand.

Determine ATM Switch Suitability Any ATM switch that processes transit traffic (that is, connections that do not either originate or terminate on any of the port networks directly attached to it) may require special engineering. This is possible if the number of trunks on the ATM switch is more than one. If this is the case, the calculator first attempts to determine if the application is feasible despite the transit traffic. If it is, it reports the feasibility as YES or PROBABLY.

Installing a DEFINITY Server ATM-PNC Installing and Testing Network Synchronization An Avaya MultiVantage on DEFINITY Server ATM-PNC requires network synchronization for DS1 circuit packs not to slip relative to the LEC/IXC switches. The ATM switch serves as the sync reference source for the DEFINITY Server. The ATM switch, in turn, derives primary and secondary sync. To accomplish this, the most common option is to use synchronization expanders (splitters).

Installing a DEFINITY Server ATM-PNC Setting Up ATM Network Duplication ATM-PNC configurations without duplicated SPEs can be supported with duplicated EPN connectivity to other points on an ATM network, or ATM network duplication. These points can be on separate ATM switches, the same ATM switch, or directly connected to an ATM-WAN. With respect to port network connectivity, there is no difference in performance between ATM network duplication and critical reliability.

Processor port network (PPN) 3. Expansion port network (EPN) 2. ATM switch 4. ATM WAN spare processor 5. ATM network fault Figure 3-10. WAN Spare Processor (WSP) configuration WSPs continually monitor the administered connection(s) to the main PPN to determine if the PPN is actively communicating with EPNs.
Installing a DEFINITY Server ATM-PNC ATM-network failures can also include faults/problems: ■ in the ATM switch. ■ in the main PPN. ■ within a link. ■ in the ATM network’s fiber-optic cables and connections. When WSPs are initially administered, their state is standby (the normal state). When there is a break in the ATM network, a WSP goes from standby to active.
Installing a WAN Spare Processor Priority administration ■ Each WSP is assigned a priority from 1 (the first PN to take over) to 15 (last PN to take over.) ■ Ensure the integrity of the priority administration, because the system does not prevent 2 WSPs from having the same priority. ■ A WSP can also have no priority, called a blank priority. A WSP that is administered with a blank priority plays dead, that is, it does not monitor any other WSPs and never become active.
Installing a DEFINITY Server ATM-PNC Design considerations When installing the WSP, ensure that the WSP configuration matches the main PPN configuration as show in Figure 3-11.

Installing a WAN Spare Processor ■ If using Avaya ASP Manager (formerly DTA) the TN799B/C/DP C-LAN circuit packs must be in the same carriers and slots in the main PPN and WSPs. ■ When registering the WSPs with INADS, give them the Installation Location (IL) number for the main PPN and the number of the WSP (1-15). NOTE: This is the administered WSP number, not the priority number.
Installing a DEFINITY Server ATM-PNC Other hardware If you are using Avaya ASP Manager (formerly DTA) to copy translations, you must install a TN799B or later Control LAN (C-LAN) circuit pack in the main PPN and each WSP. Alarming strategy The alarm strategy rules for the ATM WSPs are as follows: ■ When a WSP is active, it generates a LIC-ERR major alarm on the PPN and begins a 6-day countdown timer before the system goes into No-License mode. This is normal.

Administering ATM-PNC and ATM-CES After the hardware is upgraded for Avaya MultiVantage software on a DEFINITY ATM-PNC or ATM-CES, you must administer the ATM switch and the Avaya DEFINITY® Server to finish the process. Administration procedures are: ■ Accessing Switches for Administration ■ Acquiring ATM Addresses ■ Administering ATM Switch ■ Administering DEFINITY Server.
Administering ATM-PNC and ATM-CES Acquiring ATM Addresses Equipment that interfaces with an ATM switch must have a unique 40-digit (20-byte) ATM address. These 40 characters are divided into sectors as Table 5-1 shows: Table 5-1. ATM addressing Hex digit position Length (hexadecimal) 1-26 26 Network prefix that identifies a particular ATM switch in the network. 27-38 12 End system identifier (ESI) identifies each end-station connected through an ATM switch.

Troubleshooting Are talk paths being established between port networks? Diagnostics. ■ Can you talk both ways on a set on one port network dialed from another port network and vice versa? — The CBR (Constant Bit Rate) virtual circuits (VCs) between ATM switch PPN port and ATM switch EPN port are used for talk paths between port networks (PPN to EPN, EPN to PPN, or EPN to EPN). — They are established when calls are first setup between port networks.
Troubleshooting ATM-CES Incorrectly typed or omitted EPN route or end system identifier (ATM switch) Symptoms Talk paths are one-way, from the PPN to the EPN: you can hear tones from the PPN end station to the EPN end station but not vice versa. Because the signaling channels are bidirectional virtual circuits (VCs) established from the PPN to the EPN, these can be routed correctly and come up just fine.

Troubleshooting ATM-PNC Conserving ATM bandwidth Port Networks in a DEFINITY ATM-PNC configuration, when used with the Avaya access concentrators or other ATM switches interfacing to bandwidth-constricted or congested facilities, can incur contention for bandwidth, resulting in failed call completions. Figure 6-5 represents a DEFINITY ATM-PNC configuration in which Inverse Multiplexing for ATM (IMA) is used going into and coming out of the network cloud.
Troubleshooting In this configuration connections from the DEFINITY Server switch and the ATM backbone switch and to the ATM access concentrator are OC-3/STM-1 through the TN2305X/TN206X ATM interface circuit packs over fiber optic cable. When traffic exceeds the capacities of the IMA links, contention for access to the ATM network occurs. In such cases, SVC setups requested by the DEFINITY Server can be denied by the ATM network and associated components, and calls are not completed.
Troubleshooting ATM-PNC SVC latency commands Two reports are available to help monitor the ATM network: 1.

ATM Switch Feature Interactions ATM Feature Interactions The following sections summarize the effects of ATM-WAN PNC on various features because of: 1. Location assignments in a widely distributed switch 2. Cell delivery delays and race conditions that occur on the ATM-WAN. The features affected by these conditions are listed in Table B-6. Table B-6.
ATM Feature Interactions Table B-6. Release 7 or later ATM feature interactions (Continued) Affected by Feature Location Race Condition AUDIX X X Automatic Call Distribution (ACD) Description Remedy If a call goes to AUDIX, and the assigned AUDIX is far across the WAN, a race condition can exist between alerting with answer by AUDIX, and establishment of an inter-port-network connection through the ATM WAN. If the WAN loses, the AUDIX announcement could be clipped or lost.
ATM Switch Feature Interactions Table B-6. Release 7 or later ATM feature interactions (Continued) Affected by Race Condition Feature Location Description Call Forwarding X When call forwarding is activated and a call is actually forwarded, the forward-to digits are analyzed, and the call is routed, according to the location, tenant partition, and partition group assigned to the forwarded endpoint, not according to the caller’s properties and permissions.
ATM Feature Interactions Table B-6. Release 7 or later ATM feature interactions (Continued) Affected by Feature Location Modem Pooling X Race Condition Multimedia Description Remedy Delayed connections to and through a modem pool can lead to failed modem training sequences. Modern modems are more than twice as fast as the fastest modems supported by a modem pool. The multimedia feature builds a conference using MMIs and VCs in a single port network to minimize the number of timeslots.
ATM Switch Feature Interactions Table B-6. Release 7 or later ATM feature interactions (Continued) Affected by Race Condition Feature Location Description Ten-Digit to Seven-Digit Conversion X Supports 10-to-7 digit conversion by providing location-dependent routing and location-dependent home-NPA definition. Time-of-Day Routing X The system clock, which determines time-of-day routing transitions, permits administration of a daylight savings time rule, if desired.
