Motorola V3229 Operating Instructions - Page 44

Operation Note: For a 2- or 4-wire leased line connection to succeed one modem must be configured as forced answer and the other modem as normal originate. Both modems should have only one protocol, MNP or LAPM, enabled and PROTOCOL FALLBACK must be disabled. DCE line speed must be the same for both modems. 4-Wire Operation In 4-wire operation, the modem is a full-duplex, leased line modem requiring a dedicated 4-wire leased line. Only point-to-point dedicated leased lines are supported. A V.32 or V.33 training sequence may be selected for use during 4-wire leased line operation using S31. Refer to S31 in Chapter 6 for options. The 4-wire leased line connects to the TELSET/ LEASED LINE jack on the modem rear panel. Dialing is not necessary. When connected via leased line the modems will train and begin communicating with each other. The DIAL jack can be used to connect a 2-wire PSTN line for dial backup. 2-Wire Operation In 2-wire operation, the modem is a full-duplex modem able to operate over 2-wire leased or PSTN lines. 2-WIRE LEASED LINE OPERATION The 2-wire leased line is connected to the TELSET/ LEASED LINE jack; the DIAL jack connects to a 2wire PSTN line for dial backup. The leased line connects the local and remote modems directly and dialing is not necessary. One of the modems must be configured for forced answer. When connected via V.3229 / V.3229L -7
