================================= VEN-TEL, INC. 2400 PLUS II Full Featured Modem With Security ================================= ================================================================ The Ven-Tel 2400 Plus II External Modem provides 2400 bps data transmission over both dial-up and leased lines. Fully compatible with the industry standard AT command set, it offers three levels of security and supports MNP Levels 2, 3, and 4 error correction. In addition, it provides MNP Level 5 data compression allowing throughput up to 4800 bps. ================================================================ FULL FEATURED MODEM The 2400 Plus II External Modem provides all of the features needed to accommodate even the most sophisticated applications. Offering full duplex communication at 2400 bps, 1200 bps, and 300 bps, it permits transmission over two-wire dial-up or leased lines and supports both synchronous and asynchronous operation. Designed according to CCITT V.22bis specifications, it also supports CCITT V.22, Bell 212A, 103 and 113. PREVENTS UNAUTHORIZED ACCESS Access security restricts remote modem users from accessing the local area network (LAN) or local PC, reducing the possibility of compromising confidential data or uploading damaging files. Three user access levels of security are provided - Callback, Programmed Callback, and PassThrough Access - as well as local and remote security supervisor access. All remote user names, passwords, and callback numbers are stored in the non-volatile memory of the 2400 Plus II. REMOTELY CONFIGURE THE 2400 PLUS II Ven-Tel's proprietary Remote Options Access and Downloading (R.O.A.D) enables access and reconfiguration of the 2400 Plus II from any location, providing optimum control of the network. Through R.O.A.D access, configuration issues may be easily solved with a simple phone call. ERROR CORRECTION GUARANTEES ACCURATE TRANSMISSION The 2400 Plus II provides error correction using MNP Levels 2, 3, and 4 and is compatible with the international error correction standard V.42. Therefore, 100% accuracy is assured whether transmitting over normal or poor line conditions. DATA COMPRESSION SAVES TIME AND MONEY With MNP Level 5 data compression, the 2400 Plus II offers throughput up to 4800 bps. Transmission time is significantly reduced, resulting in lower telephone line charges. ================================================================ FEATURES ================================================================ Model Number..................EC2400-33 (2400 Plus II) Compatibility.................CCITT V.22bis - 2400 bps CCITT V.22 - 1200 bps Bell 212A - 1200 bps Bell 113 - 300 bps Bell 103 - 300 bps Modem Data Rate...............Asynchronous: 2400/1200/300 bps Synchronous: 2400/1200 bps DTE Data Rate.................9600/2400/1200/300 bps Data Format...................Asynchronous: 10 bit serial binary Synchronous DTE Interface.................EIA RS232C Telephone Line Interface......RJ11C Modulation....................QAM at 2400 bps DPSK at 1200 bps FSK at 300 bps Error Correction..............MNP Levels 2, 3, and 4 CCITT V.42 compatible Data Compression..............MNP Level 5 Line Requirements.............Two-wire leased line Two-wire dial-up (PSTN) Line Impedance................600 Ohms Transmitter Timing............Internal or external, software selectable (synchronous mode) Transmitter Output Level......-9 dBm Receiver Sensitivity..........-48 dBm Test Modes....................Local analog loopback, local digital loopback, remote digital loopback with self-test, and local analog loopback with self-test Physical Dimensions: Height...................1.25" Depth....................9.5" Width....................6.5" Weight...................2.2 lbs.
