The 108600 converts digital signals from EuroCom A/B to EuroCom C and visa versa. It is used when the distance between relevant equipment units is too long for EuroCom A/B transmissions. It is also used when equipment units with different interface types are to be connected. The TDM bit-rate can be selected between 256, 512, 1024 or 2048 Kbps. When transmitting at the highest bit rate (2048 Kbps), and with the use of a dry field cable, the cable length can be up to 1 km.
The 108700-01 unit utilizes time division multiplexing to convert up to four duplex EuroCom D/1 “B” interfaces to a single switch selectable choice of EuroCom D/1 interface C or E1 per ITU G.703. It is rack mountable and suitable for either mobile or fixed installations. The LTU is also suited for applications where the distance between equipment units is too long for EuroCom D/1 interface B transmissions or when standard cable lengths are too short. Additionally, it is used in applications where equipment units with different interface types are to be connected. The LTU is powered by 24 VDC. A two-wire, 16 kbps engineered orderwire (EuroCom “F” EOW) capability is provided.
The 108700-02 LTU-V.35 coverts the clock, data, control and handshaking signals of a single ITU-T V.35 interface to EuroCom D/1 interface C. It is rack mountable and suitable for either mobile or fixed installations. The LTU-V.35 is suitable for applications where the distance between equipment units is too long for ITU-T V.35 transmissions. The LTU is powered by 24 VDC.
