TL-130500-1001 DATA EQUIPMENT/12.0 The data system can handle a maximum of 120 ENGINEERINGdata ports. This section provides a general configuration overview, detailed configuration rules and limitations, and procedures for engineering the data system. The following parameters describe the customer requirements to configure or add on a data switch: APM= Tl + T2 - T3 where Tl = number of asynchronous data terminal ports requested (maximum speed = 19.2 Kbps) (VPLO or VP20)T2 = number of asynchronous host ports requested (maximum speed = 19.2 Kbps) (VPLO or VP20)T3 =number of Digital Featurephones with APM requested (VPLO or VP20)SPM= Sl + s2 where Sl= number of X.25 ports < = 19.2 Kbps (using RS-232-C interface) (VPLO or VP20)S2 = number of X.25 ports > = 9.6-64 Kbps (using V.35 interface) (VPLl or VP21) Computing Hardware12.1 To compute the required hardware quantities, first Quantitiesdetermine the number of data ports needed. There are five types of ports: l Terminals - Asynchronous (with or without modems) - X.25 (with or without modems) . Host ports - Asynchronous (with or without modems) - X.25 (with or without modems) l Number of modems in each modem pool (if required) l Data network connections l Network interface connections SVR 52108187S-l 83
TL-130500-1001 Compute the hardware quantities as follows: 1. Compute the total of asynchronous terminals (with and without modems), plus asynchronous host ports (with and without modems), plus asynchronous modems in modem pools. This total is the number of APMs or DPF/APM required. 2. Determine any other DFP/APM required. 3. The X.25 terminals and host ports must be split into two groups, depending upon line speed. Those which operate at 19.2 kbps or less fall into the first group, which uses a SPM with an RS-232-C connector. Those which operate above 9.6 to 64 Kbps are handled separately because they require an SPM with a V.35 connector. 4. Total the X.25 terminals, X.25 host ports, and public data network connections operating at 19.2 kbps or less. This gives the total number of SPMs with RS-232-C connectors required. These will be connected to VPLC type 0 line cards. 5. Total the X.25 terminals, X.25 host ports, and public data network connections operating at line speeds between 9.6 and 64 Kbps. This gives the total number of SPMs with V.35 connectors required. These will be connected to VPLC type 1 line cards. 6. To determine the required number of VPLC type 0 line cards, add the number of APMs (from step 1) and the number of SPMs with RS-232-C connectors. Divide this by 8, rounding up if the answer is a fraction. 7. To determine the number of VPLC2 cards, add the number of DFP (with and without APM). Divide this number by 8, rounding up if the answer is a fraction. 8. To determine the required number of VPLC type 1 line cards, divide the number of SPMs with V.35 connectors by 2, rounding up if the answer is a fraction. NOTE: Since these VPLC type 1 cards control the system’s high-speed links, it is often advisable to order and configure an extra or back-up VPLC type 1 card for links to public data networks. (Remember, each VPLC type 1 has only two usable circuits.) 9. Determine the number of NIC cards. S-l 84 8187SVR 5210

These figures also provides placement of PR, PBE, PBT, and UCB functioning as bus terminators. Figures 12.2 and 12.3 represent possible LPB configurations. The recommended arrangement for most applications is to use a complete file (A & B, C & D) for the LPB. Put voice cards in the unused PCMUSs. This will make the best use of both the data and voice bus capacity of the file. Put LPB 0 in the Get Started File whenever possible (see Figures 12.4, 12.5, 12.6). INOTES:I 0 Placement of bus extender and terminators can be reversed. e In the following configurations, the UCB is configured to function as a bus terminator card (see Figure 12.7).
