Converters(ES2703) Description

The ES2703 Access Unit are single port access units for Unframed E1 services. The Data Port rate is fixed at 2048kbps (Unframed E1 only). User data is transparently transmitted on the E1. The main E1 link may be clocked from the recovered receive clock (LBT), from the data port, or from an internal oscillator. The data channel interface is RS-530 standard on a DB25F connector. Adapter cables are available for V.35, X.21 and RS-449. The G.703 port provides for either 75 Ohm unbalanced connection via BNC connectors or 120 Ohm balanced connection via RJ-45. The ES2703 DIP switches, located under the unit, provide for easy setup and control of all functions.
