The VCL-30 E1 Interface operates at a primary rate of 2.048 MBits/Sec and provides a host of features including, channel drop and insert facility, high-speed data ports for digital communication links - including internet access, wide area networking, over a network of VCL-30, E1 multiplexers, for voice and data applications. The VCL-30 has an effective, Windows based "Network Management System", which may be used for configuring the system and subsequent remote monitoring, management and control of the inter-connected systems in the network. An extensive set of alarms, for easy maintenance are provided in the system. The system supports low speed synchronous / asynchronous V.24 interface and high speed synchronous V.35, G.703 data interfaces. The equipment also supports FXO, FXS and inter-exchange E&M interface used for inter-connecting telephone exchanges ("junction mux application").
The available data interface options include:
The VCL-30 offers an excellent flexibility on the choice of transmission medium over which it may be deployed. The transmission medium may be either twisted copper cable pairs, optical fiber cable, or wireless.

Applications of VCL-30
The VCL-30 is part of the digital hierarchy to provide 30 channels at 64Kbps. The individual channels are used to provide voice telephony, digital data to support point to point or networked applications and video conferencing applications. The VCL-30 is also ideal for cellular infrastructure applications, in providing cell - switch connectivity.
Other important applications include drop and insert (add-drop) facility, voice conferencing, hotline facility, high-speed data ports for digital communication links - including internet access, wide area networking and much more.
The system supports a full range of voice interfaces with user programmable speech output levels, which include:
The VCL-30 provides 30 digital data channels @ 64Kbps per channel, to all the subscribers. The VCL-30 provides V.24 (RS232), V.35, G.703, iDSL (ISDN DSL) leased line interface and 10BaseT Ethernet G.703, co-directional, synchronous data interface @ 64Kbps.
