Comtrend’s CT-2000 is a flexible multi-service platform, for voice and data applications using time division multiplexing technology. Featuring powerful timeslot interchange (TSI) capability, the CT-2000 can work as a: flexible STM-1/T1/E1 multiplexer, 1/0 digital cross-connect system, rack-mounted CSU/DSU, or T1/E1 converter. The CT-2000 utilizes common interface modules to perform a wide-range of applications, so it can reduce space requirements and inventory costs.

With its high-density interface units, the CT-2000 is excellent for carrier-class deployment. For STM-1 SDH multiplexer application, up to 63 E1 lines can be cross-connected to the STM-1 interface, with direct access to the SDH backbone. For T1/E1 flexible multiplexer application, up to 64 T1/E1 lines can be supported. The versatile tributary interface units provide multiple data and voice services on the same shelf. The interface unit is equipped with remote control capability on CPE devices to achieve full network management.

Comtrend’s FM-60 is a flexible transmission system, which provides voice and data applications by time division multiplexing and demultiplexing on 2.048 Mbps E1 signals. Timeslot interchange technique is applied to provide timeslot assignment and timeslot interchange capability, so that any 64 Kbps or Nx64 Kbps user-signal can be assigned and cross-connected to any E1 timeslot.

The CT-210 MSDSL NTU enables symmetric transmission over a single twisted pair of telephone lines. Based on 2B1Q line coding, the CT-210 supports multiple transmission rates ranging from 144 Kbps to 2,320 Kbps. Line rates can be user configured or rate-adapted to line condition.

The CT-210 provides industry standard V.35 interface it is suitable for leased line applications such as video conferencing, Internet access, and digital data network (DDN) access, etc

CT-128, a desktop Multiple Rate IDSL NTU, combines the Network Terminating Unit (NTU) with the multi-rate Data Service Unit (DSU) in one small delicate enclosure. It can transport data at speeds of up to 128 Kbps, full duplex, over an ordinary 2-wire telephone line. This high bandwidth availability is made possible using the ISDN U-Interface 2B1Q line coding technique, an industry standard for digital transmission on metallic facilities.

CT-128 offers flexible applications for asynchronous and synchronous transmission. It supports one data channel operating at speeds from 2.4 Kbps to 128 Kbps.
