SVR 5210ORDERING THE DATA SYSTEMTL-130500-1001 13.0 The PD-200 data option must be ordered as a custom system. When ordering the data system, first complete a frame layout worksheet. The frame layout worksheet is located in the Hardware Ordering Guide (FB-41640). After the layout sheet has been completed, fill out the hardware editing sheets (FM-41460). Submit copies of the completed sheets. Information for completing the layout sheet is given in Figure 13.1. Notes that provide an explanation of information in Figure 13.1 follow: NOTES: 1. Determine number of DFP/APM, APM, SPM low-speed and SPM high-speed connections. a. Determine number of VPLO cards and/or VP20 cards used for DFP/APMs, APMs, and low-speed SPM connections. b. Determine number of VPLl cards and/or VP21 cards used for SPM high-speed connections. Since the VPLl or VP21 cards control the system’s high-speed data links, it is recommended to configure and order a back-up card for connection to the PDN (Public Data Network). c. There is a system limit of 8 VPLC (any type) per file and16 VPLC (any type) per system maximum 2. Maximum number of LPBs for this release is two. Each LPB can support up to 12,000 mini-packets per second. 3. ADMP A and C, UCB, PR, and PBEiT4. See voice ordering section for further details. 8187S-205

SVR 5210TL-130500-1001 ATTENDANT15.0 The Attendant Console (Figure 15.1) is a compact, CONSOLEmicroprocessor-controlled, desk-top console unit. It provides control and flexibility for processing calls through the system while on-line (in use). The user can place the console in other control modes during nightime, maintenance, or unattended periods. The system supports a maximum of two Attendant Consoles. The Attendant Consoles are remotely located from the equipment cabinets. The Attendant Console contains compact electronics and all controls and indicators needed for complete monitoring and control of calls through the system. Both incoming and outgoing calls can be answered, extended, camped on, put on hold, or released from the console by depressing various pushbuttons. Each Attendant Console uses five EPROM (Erasable Programmable Read-Only Memory) chips that contain the generic software that determines the functional operation of the Attendant Console.

--TL-130500-1001 Attendant Console System Interface Attendant Console Hardware Light Emitting Diode15.1 The Attendant Console interfaces with the system via the PLCC and the ATT12 cards, located in PCtvlUS (Pulse Code Modulation Universal Slots). It is recommended to place these cards in adjacent card slots for easier installation and maintenance. 0 PLCC (line circuit card) FB-17254-A provides the analog channel for both DTMF signaling and voice communication between the Attendant Console and the system. The analog channel is connected to the system via tip and ring connections to one port of the line card. 0 ATT12 (Attendant Interface) FB-17208-A provides the digital data link channel connection to the system. The data link is a full-duplex, 1,200 baud, current loop. NOTE: The ATT12 and PLCC cards are described on Table 3.6. Attendant Console interface cabling is described in TL-130300-l 001. 15.2 The Attendant Console includes the following features: 0 26-pushbutton keyboard 0 12 key dial pad 0 Call-waiting queue lamp 8 Optional headset/handset and associated jacks l Connect to BLDU (Busy Lamp Display Unit) (Optional) 0 32-alphanumeric character LED display for displaying class of service, equipment identity, type of call, dialed digits, time of day, and system alarm information 15.3 An alphanumeric, 32-character display LED (Light Emitting Diode), located across the top of the Attendant Console, provides call information to the user including the type of call, class-of-service marks, and equipment identity. The type of call indication is present as long as the attendant is servicing the call and during attendant recalls. Possible call types include FX and Tie. System fault alarm information is displayed in the type of call position if the ALARM pushbutton is depressed. s-21 08187SVR 5210
Headsets General Information for Attendant Console Software and Operation Attendant Call DistributionSVR 5210TL-130500-1001 15.4 The Attendant Console has two sets of headseuhandsetjacks: a rear jack for supervisory monitoring and a side jack for attendant use. The headset/handset must be plugged in for the Attendant Console to operate in the on-line mode. Should the headset/handset be unplugged, the Attendant Console defaults to the Night 1 mode, and is considered busy by the operating system software. Diagnostic self tests can be initiated while in the Night 1 mode. 15.5 For dual Attendant Console operation, attendant-seeking traffic is distributed evenly between the two attendants. When the headset/handset is removed from the jack, the Attendant Console is considered unstaffed and the call is diverted to a second Attendant Console (the Attendant Console with the headset/handset removed is placed in the Nl mode of operation). Night answer modes Nl and N2 are data base programmable to provide UNA (Universal Night Answer), PNA (Predetermined Night Answer), or a combination of both night answer services. Removing the headset/handset turns off all lamps on the console and sends an unstaffed message to the system. All calls to this console are then cleared. 15.6 Calls to the Attendant Consoles are distributed evenly, but the number of loops used for incoming calls is a programmable system feature. Either 1, 2, 3, or 4 loops may be programmed to receive incoming calls. Do not to enable the fourth loop since this could prevent the attendant from making an outgoing call during an emergency. Regardless of the selected number of loops programmed for incoming calls, console 1 receives the first call on LOOP 1, console 2 receives the next call on LOOP 1, and so on, until all available consoles have a call on LOOP 1. Additional incoming calls either ring into LOOP 2 on each available console (if programmed), following the same sequence, or they are placed in the call waiting queue until an incoming loop becomes idle on any console. The system preferentially fills preceding loop levels before either moving into the next higher loop level or placing a call in Call Waiting Queue. When programmed for overflow, the universal answer mode is also activated when the second call-waiting queue is reached. 8167s-21 1
TL-130500-1001 In a single console operation, calls can automatically ring into LOOP 1 through LOOP 4 sequentially, depending upon the system programming. All calls will remain in the call waiting queue until a loop becomes idle. An attendant releases’ an active loop by depressing the POS’ RLSE, HOLD, or CAMP-ON pushbutton, or another LOOP pushbutton. Upon release, the next call in the call waiting queue is presented to the attendant. For dual Attendant Console operation, attendant-seeking traffic is distributed evenly between the Attendant Console positions. Except for priority calls, all attendant-seeking traffic is queued on a FIFO (First-In, First-Out) basis. Only one new call is sent to the attendant at a time. The attendant can release from the active loop by depressing the POS RLSE, HOLD, or CAMP-ON pushbutton, or another LOOP pushbutton. When the button is released, the next call in the call waiting queue will be sent to the attendant.Attendant15.7 A 24-VAC transformer, connected to a local 115VAC Console Bowerpower source or a-48 VDC power supply, powers the Attendant Console. See TL-130300-1001 for a description of the Attendant Console power connections. NOTE: Input to the Attendant Console should not exceed -54 volts DC. 8187SVR 5210
