--Image: RACKABLE! Rack Mount Available --The Patton Model 2070 Series inter-face converters allow a router-or similar WAN device-with a V.24 (RS-232), V.35 or X.21 port to connect to a G.703/64k co-directional (PCM) network. Offering switchable internal, external or network clocking options, the Patton Model 2070 Series converters support bi-directional, synchronous communication at a data rate of 64 kbps.The Patton Model 2070 Series includes three variations: The Model 2070/AM plugs directly into an RS-232 DTE, and is equipped with a male DB-25 connector.The Model 2070/CM plugs directly into a V.35 DTE, and is equipped with an M/34 male connector. The Model 2070/DM plugs into an X.21 DTE, and isequipped with a male DB-15 connector at the end of a 6" (15.25cm) cable. All versions come with an RJ-45 jack for 120 ohm twisted pair network termination (termination to a 75 ohm network can be accomplished using the Patton Model 460 balun-see below).

Patton Model 2070 Series converters incorporate local loopback and G.703 loopback diagnostic modes. Diagnostic modes are controlled by a switch, or by the local DTE (V.24 or V.35 versions only). Rear panel LED indicators monitor Test Mode and Synchronization. Synchronous clock jitter is attenuated in accordance with the G.823 specification. For protection against ground loops and transient surges, the Patton Model 2070 Series converters incorporate both trans-former isolation and surge protection.

Power is supplied to the Patton Model 2070 Series converters by an external power supply. When used in a point-to-point environment, distances up to 5250 feet (1600m) are attainable using two 24 AWG (.5mm) twisted pairs.

The Patton Model 2070 Series is the perfect solution for connecting a router or other WAN device to a 64 kbps G.703 network: Their small size allows the Patton Model 2070 Series converters to plug directly into a DTE port, almost like a cable–they have no “footprint” at all! Besides their ultra-compact size, the Patton Model 2070 Series converters are also available in three DTE interface types–V.24 (DB-25), V.35 (M/34) and X.21 (DB-15)–for easy adaptation to the myriad of brands and models in the WAN hardware marketplace. Whichever 64 kbps G.703 connection you need to make, there’s likely a Patton Model 2070 Series converter that will plug right in! (These converters will operate point-to-point, too.)
