BR-CSU153
CSU
BR-CSU153 is single-port fractional T1/E1 and CSU equipment which can be connected to T1/E1 service. It has a transmission speed enabling synchronous data channels and programs. The usable speed is 56Kbps / 64Kbps or higher. This system can transmit signals of voice, data and video to users who need transmission bandwidth of 1.544Mbps in case of T1 and 2.048Mbps in case of E1 after dividing them with N×24, N×30/31 multiples. Eff ective data of DTE are sent carried in TimeSlot corresponding to T1 or E1 data fl ow. BR-CSU153 system is highly compatible with other equipment and has remarkable expandability of DTE interface.
