Use care in the selection of the controllers. Follow the configurationrules.CommunicationsThe following adapters support communications on the Model 250:• #2745 PCI Two-Line WAN IOA• #2750 PCI ISDN BRI U IOA• #2751 PCI ISDN BRI S/T IOA• #2761 Integrated Analog Modem• #9720 Base PCI WAN/Twinaxial IOA• #9771 Base PCI 2-Line WAN with Modem#2745 PCI Two-Line WAN IOASupports up to two multiple protocol communications ports when one of two (in anycombination) of the following cables are attached:• #0348 V.24/EIA232 20ft/6m PCI cable• #0349 V.24/EIA232 50ft/15m PCI cable• #0353 V.35 20ft/6m PCI cable• #0354 V.35 50ft/15m PCI cable• #0356 V.36 20ft/6m PCI cable• #0359 X.21 20ft/6m PCI cable• #0360 X.21 50ft/15m PCI cable• #0365 V.24/EIA232 80ft/24m PCI cable• #0367 Operations Console cableNote: Only one #0367 Operations Console cable is allowed per system.#2750 PCI ISDN BRI U IOA#2750 is a 4-port (8-channel) ISDN BRI (basic rate interface) full-sized PCI card. Based onthe latest DSP technology, #2750 allows connections to fax or data modems connected to thetelephone network with analog phone lines as well as to other IDSN devices. Each portconsists of 2B+D configuration. The #2750 is the “U”-bus (2 wire) version IOA.• For data mode support, B-channel supports digital data at 64 Kbps.• For modem mode support, B-channel supports V.90 and lesser modulations.A wrap cable/plug and four 30-ft RJ-45 to RJ-45 network cables are shipped with each card.The #2750 IOA supports full duplex mode. It supports the PPP, IDLC, and Fax protocols.
