DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing data calls 428 Administered Connection 15 Interactions nAbbreviated Dialing Use Abbreviated Dialing entries in the Destination field. Entries must comply with restrictions. nBusy Verification of Stations and Trunks This feature does not apply to access endpoints because they are used only for data. nCall Detail Recording For an AC that uses a trunk when CDR is active, the origination extension is the originator of the call. nClass of Restriction Reserve a COR for AC endpoints and SDDN trunks. This restricts endpoints that are not involved in AC from connecting to SDDN trunks or endpoints involved in AC. nClass of Service/Call Forwarding Assign to an AC endpoint a COS that blocks Call Forwarding activation at the endpoint. nDigital Multiplexed Interface (DMI) Use DMI endpoints as the destination in an AC. DMI endpoints do not have associated extensions, so do not use them as the originator in an AC. nFacility Test Calls The feature does not apply to access endpoints because an access endpoint acts as an endpoint rather than as a trunk. nModem Pooling If you require a modem in an AC, one is inserted automatically. If no modem is available, the connection is dropped. nNon-Facility Associated Signaling (NFAS) and D-Channel Backup Auto restoration for an AC that is initially routed over an NFAS facility may fail if the only backup route is over the facility on which the backup D-channel is administered. The backup D-channel may not come into service in time to handle the restoration attempt.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing data calls 429 Modem Pooling 15 nSet Time Command When you change the system time via the set time command, all scheduled ACs are examined. If the time change causes an active AC to be outside its scheduled period, the AC is dropped. If the time change causes an inactive AC to be within its scheduled period, the switch attempts to establish the AC. If any AC (scheduled or continuous) is in retry mode and the system time changes, the switch attempts to establish the AC. nSystem Measurements Access endpoints are not measured. All other trunks in an AC are measured as usual. Modem Pooling Modem Pooling allows switched connections between digital-data endpoints (data modules) and analog-data endpoints via pods of acoustic-coupled modems. The analog-data endpoint is either a trunk or a line circuit. Data transmission between a digital data endpoint and an analog endpoint requires conversion via a modem, because the DCP format used by the data module is not compatible with the modulated signals of an analog modem. A modem translates DCP format into modulated signals and vice versa. Modem Pooling feature provides pools of integrated-conversion modems and combined-conversion modems. Integrated-conversion modem pools have functionality integrated on the Pooled Modem circuit pack, providing two modems. Each one emulates a TDM cabled to a 212 modem. Integrated are modem pools not available in countries that use A-law companding. Combined-conversion modem pools are TDMs cabled to any TDM-compatible modem. Combined-conversion modem pools can be used with all systems. The system can detect the needs for a modem. Data calls from an analog-data endpoint require that the user indicate the need for a modem, because the system considers such calls to be voice calls. Users indicate this need by dialing the data-origination access code field on the Feature Access Code screen before dialing the digital-data endpoint. The system provides a Hold Time parameter to specify the maximum time any modem can be held but not used (while a data call is in queue).
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing data calls 430 Modem Pooling 15 Administering Modem Pooling For Integrated modem poolings: 1. On the Modem Pool Group screen, administer all fields. Refer to ‘‘ Modem Pool Group’’ on page 829 for more information. 2. On the Feature Access Code screen, administer the Data Origination Access Code field. Refer to ‘‘ Feature Access Code’’ on page 633 for more information. 3. On the Data Module screen, administer all fields. Refer to ‘‘ Data modules’’ on page 572 for more information. For Combined modem poolings: 1. On the Modem Pool Group screen, administer all fields. Refer to ‘‘ Modem Pool Group’’ on page 829 for more information. 2. On the Feature Access Code screen, administer the Data Origination Access Code field. Refer to ‘‘ Feature Access Code’’ on page 633 for more information. Considerations nOn data calls between a data module and an analog-data endpoint, Return-to-Voice releases the modem and returns it to the pool. The telephone user connects to the analog-data endpoint. nFor traffic purposes, the system accumulates data on modem-pooling calls separate from voice calls. Measurements on the pools also accumulate. nModem Pooling is not restricted. Queuing for modems is not provided, although calls queued on a hunt group retain reserved modems. nAvoid mixing modems from different vendors within a combined pool because such modems may differ in transmission characteristics. nEach data call that uses Modem Pooling uses four time slots (not just two). As a result, heavy usage of Modem Pooling could affect TDM bus-blocking characteristics. nTandem switches do not insert a pooled modem. The originating and terminating switches insert a pooled modem.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing data calls 431 PC Interface 15 Interactions nCall Detail Recording Data call CDR records the use of modem pools on trunk calls. nData Call Setup Data calls to or from a TDM cannot use Modem Pooling. nData Privacy and Data Restriction The insertion of a modem pool does not turn off Data Privacy or Data Restriction. nData-Only Off-Premises Extensions Calls to or from a Data-Only Off-Premises Extension cannot use Modem Pooling, when this type of digital-data endpoint uses a TDM. nDMI Trunks If you place a data call from a local analog-data endpoint to a DMI trunk, you must dial the data-origination access code to obtain a modem. Data calls on DMI trunks to local analog-data endpoints automatically obtain modems. nDS1 Tie Trunk Service Connect modems used for Modem Pooling to AVD DS1 tie trunks via Data Terminal Dialing or by dialing the feature-access code for data origination. PC Interface The personal computer (PC) Interface consists of the PC/PBX platforms and PC/ISDN Platform product family. These products are used with DEFINITY ECS to provide users of IBM-compatible PCs fully-integrated voice and data workstation capabilities. Two groups of different configurations are available for PC Interface: group 1 uses Digital Communications Protocol (DCP) and group 2 uses the ISDN-BRI (Basic Rate Interface) protocol. The group 1 configurations consist of DCP configurations that use a DCP expansion card) in the PC to link to the switch. Group 1 (shown in Figure 12) uses the following connections: nThe PC Interface card plugs into an expansion slot on the PC. The card has 2 standard 8-pin modular jacks (line and phone). nThe digital phone plugs into the phone jack on the PC Interface card.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing data calls 432 PC Interface 15 nThe line jack on the card provides a digital port connection to DEFINITY ECS. nThe distance between the PC Interface card and the PBX should be no more than 1524m for 24-gauge wire or 1219m for 26-gauge wire. Figure 12. DCP PC interface configuration (Group 1) The group 2 configurations link to the switch using a PC/ISDN Interface card installed in the PC. This group can include a stand-alone PC terminal, or up to 4 telephones, handsets, or headsets. Group 2 (shown in Figure 13 ) uses PC/ISDN Interface cards (up to four cards) which plug into expansion slots on the PC. These cards each provide 2 standard 8-pin modular-jack connections for both line connections (to the switch) and phone connections. A standard 4-pin modular jack is also available for use with a handset or headset. Figure Notes 1. IBM-compatible PC with DCP Interface card 2. IBM-compatible PC with DCP Interface card 3. DCP4.

ISDN—BRI PC interface configuration (Group 2) PC Interface users have multiple appearances (depending on the software application used) for their assigned extension. Designate one or more of these appearances for use with data calls. With the ISDN-BRI version, you can use up to 4 separate PC/ISDN Interface cards on the same PC. Assign each card a separate extension, and assign each extension one or more appearances. The availability of specific features depends on the COS of the extension and the COS for the switch. Modem Pooling is provided to ensure general availability of off-net data-calling services. Figure Notes 1. ISDN telephone 2. PC with application 3. Handset or Headset 4.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing data calls 434 PC Interface 15 Security There are two areas where unauthorized use may occur with this feature: unauthorized local use and remote access. !SECURITY ALERT: Unauthorized local use involves unauthorized users who attempt to make calls from a PC. The PC software has a security setting so users can place the PC in Security Mode when it is unattended. You also can assign Automatic Security so that the administration program on the PC is always active and runs in Security Mode. This mode is password-protected. !SECURITY ALERT: Remote access involves remote access to the PC over a data extension. Remote users can delete or copy PC files with this feature. You can password-protect this feature. Refer to the BCS Products Security Handbook for additional steps to secure your system and to find out about obtaining information regularly about security developments. Administering a PC interface 1. On the Station screen, set the Type field to pc. Considerations nUse the Function Key Module of the 7405D with PC Interface. nBRI terminals normally are initializing terminals and require you to assign an SPID. The PC/ISDN Platform (Group 2), in a stand-alone configuration, is a non-initializing BRI terminal and does not require you to assign a SPID. — Set a locally-defined terminal type with General Terminal Administration — Define the terminal type as a non-initializing terminal that does not support Management Information Messages (MIM). — Assign the PC/ISDN Platform with an associated (initializing) ISDN-BRI telephone (such as an ISDN 7505) using a SPID. — Assign the station (using a locally-defined terminal type) to take full advantage of the capabilities of the PC Interface. This terminal type is also non-initializing with no support of MIMs.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing data calls 435 Wideband Switching 15 nDo not use telephones with data modules with the PC Interface. (You can still use 3270 Data Modules if you also use 3270 emulation). If you attach a DCP data module or ISDN data module to a telephone that is connected to a PC Interface card, the data module is bypassed (not used). All the interface functions are performed by the interface card even if a data module is present. nThe 7404D telephone with messaging cartridge cannot be used with PC Interface. However, the 7404D with PC cartridge can be used, but only with Group 1 configurations. Wideband Switching Wideband Switching provides the ability to dedicate 2 or more ISDN-PRI B-channels or DS0 endpoints for applications that require large bandwidth. It provides high-speed end-to-end communication between endpoints where dedicated facilities are not economic or appropriate. ISDN-BRI trunks do not support wideband switching. Wideband Switching supports: nHigh-speed video conferencing nWAN disaster recovery nScheduled batch processing (for example, nightly file transfers) nLAN interconnections and imaging nOther applications involving high-speed data transmission, video transmission, or high bandwidth Detailed description ISDN-PRI divides a T1 or E1 trunk into 24 (32 for E1) channels, where one channel is used for signaling, and all others for standard narrowband communication. Certain applications, like video conferencing, require greater bandwidth. You can combine several narrowband channels into one wideband channel to accommodate the extra bandwidth requirement. DEFINITY ECS serves as a gateway to many types of high-bandwidth traffic. In addition, DS1 Converter circuit packs are used for wideband switching at DS1 remote EPN locations. They are compatible with both a 24-channel T1 and 32-channel E1 facility (transmission equipment). They support circuit-switched wideband connections (NxDS0) and a 192 Kbps packet channel.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing data calls 436 Wideband Switching 15 The following table provides information on Wideband Switching channel types. Channel allocation For standard narrowband communication, ISDN-PRI divides a T1 or E1 trunk as follows: nT1 trunks are divided into 23 information channels are 1 signaling channel nE1 trunks are divided into 30 information channels, 1 signaling channel, and 1 framing channel Certain applications, like video conferencing, require greater bandwidth. You can combine several narrowband channels into one wideband channel to accommodate the extra bandwidth requirement. DEFINITY ECS serves as a gateway to many types of high-bandwidth traffic. In addition, DS1 converters are used for wideband switching at remote locations. Performed using one of the three allocation algorithms: fixed, flexible, or floating. nFixed allocation — Provides contiguous-channel aggregation. The starting channel is constrained to a predetermined starting point. (Used only for H0, H11, and H12 calls.) nFlexible allocation — Allows a wideband call to occupy non-contiguous positions within a single T1 or E1 facility (NxDS0). nFloating allocation — Enforces contiguous-channel aggregation. The starting channel is not constrained to a predetermined starting point (NxDS0). Channel Type Number of Channels (DSOs) Data Rate H0 (T1 or E1) 6 (grouped 4 (T1) or 5 (E1) quadrants of 6 B-channels each)384 Kbps H11 (T1 or E1) 24 (on T1 - all 24 B-channels, with the D-channel not used; on E1 - B-channels 1 to 15, and 17 to 25, and B-channels 26 to 31 unused)1536 Kbps H12 (E1 only) 30 (B-channels 1 to 15 and 17 to 31) 1920 Kbps NxDS0 (T1) 2-24 128–1536 Kbps NxDS0 (E1) 2-31 128–1984 Kbps
