rTL-130500-1001Data Architectural Overview6.5 This paragraph provides an overview of the data. architecture. Asynchronous Connection6.51 Asynchronous devices (terminals, hosts, and modems, etc.) connect to the system via APMs (Asynchronous Packet Managers) or DFP/APMs, which are collocated with their devices. Except for call-control-related events (call setup, disconnect, etc.), APMs contain all processing and transmission capabilities necessary to support transmission of asynchronous data. In...

TL-130500-1001Synchronous6.5.2 Synchronous CCITT X.25 devices (hosts and public data Connectionnetworks) connect to ‘the system via SPMs, which are col- located with their devices. Connection from the SPM to its device is via an RS-232-C type or V.35 type connector. The W-232-C connectors are used for devices operating at less than or equal to 19.2 kbps, while devices operating at up to 64 kbps use the V.35 connector interface. SPMs can be configured as a DTE or DCE. Each SPM is assigned one or more...

TL-4 30500-l 001 PD-2007.0 This section provides descriptive information about PCBsPRINTED CIRCUITinstalled in a system supporting the packet data option (see BOARDSFigure 7.1). All PO-200 cards are installed into PCMUS (Pulse Code Modulation Universal Slot) card slots. All data cards occupy one card slot. In addition to the hard disk drive, floppy disk drive, and FB- 17220-BOA File Management System Data (FMSD) card, which are a part of the basic voice system, the PO-200 Data System can include the...

SW 5210 TL-130500- 1001 UCB/DCP7.2 The UCB (Universal Controller Board) houses the DCP (Data FB-17231 -A Call Processing) software. This software runs the data switching needed by the DFP/APM (Digital Featurephone with Asynchronous Packet Manager), APM, SPM, and the system. The UCB/DCP is divided into two major eight-bit microprocessor circuits. l The NETLINK microprocessor is used for communicating with the LPB (Local Packet Bus). It also runs the necessary protocols for communications over the LPB....

TL-130500-1001PR7.3 The PR (Packet Router): FB-17228-BOA l Electrically enables LPB 0 - The PR directly accesses LPB 0 off the backplane. - Since the PR activates LPB 0, the card must be at one end of that bus. It is recommendec to place the PR in card slot CO8 or DlO.NOTE: LPB 0 connects to the PR directly off the backplane. This bus can be located in either file. ,’l Receives and transmits mini-packets on LPB 0 and LPB 1 - Each PR can support 2 LPBs (LPB 0 and LPB 1). - LPB 1 is accessed by the PR...

TL-130500-1001 NIC FB-17242-ASVR 52107.5 The NIC (Network Interface Card) in coordination with a Tltrunk card set, allows PD-200 packet data to be sent over digital common carrier lines to a remote PD-200 system. The card contains two microprocessors. One microprocessor communicates with the LPB., and the other with the PCM bus. Mini-packets sent to the NIC card from the various peripherals are converted to true X.25, HDLC-type (High-Level Data Link Control) packets. These packets are in turn “chopped”...

TL-130500-1001 VPLC7.6 The VPLC (Voice Packet Line Card) used for data transfer FB-17226-Aonly provides the interface between the system LPB, PEC bus, and external synchronous/asynchronous packet managers. The card has eight circuits and is software programmable as either a type 0 or type 1 card. l When programmed as type 0 (card type VPLO):- the card can use all of its eight circuits - the card can transport asynchronous data at a rate of 19.2 Kbps (kilobits per second) and/or - the card can transport...
