Overview: GVE-Tplus is E1 to V.35/V.24/RS232 and Ethernet Converter. Other series interface RS449/RS530/X.21 also can be optional. E1 port can support BNC/75ohm and RJ45/120ohm optional. This device provides an economical digital access solution for E1 and fractional E1 network services. With a adapter cable, the device can connect to other DTE device, such as router, at data rates of 64Kbps to 2048Kbps.User data is placed into the E1 frame, using only the required number of timeslots, timeslot assignment is accomplished according to the data port speed and manual setting of DIP switches. The V.35 or V.24/RS232 and Ethernet share the 2Mbps bandwidth, the total bandwidth of the 2 interfaces must be not more than 1984Kbps.GVE-Tplus is widely used in communication network, both in WAN and LAN connection field.
