CSP-16M little channel digital transmission system

[Open/Save exploitation manual]

[Open/Save operator’s manual]

General information

      • Using of one pair of T, TP, KSPP, MKS types cable or open line.

      • Creating outstation for two-wire subscriber terminations of PBX to remote subscribers with simultaneous cable multiplexing.

      • Organization of 4/6-wires channels terminations of TFC for multiplexing junction lines of analog PBXs.

      • Data transmission over Ethernet network with the support of 100Base-TX protocol.

      • Possibility of connecting two payphones with local billing and telephone line protection against unauthorized connection.

      • Power supply of station units from 48 or 60 V battery.

      • Power supply of remote units from mains 220 VAC, remote power supply over working cable pair or from DC battery depending on constructive option and local conditions.

      • Possibility to increase the distance to outstation by organizing the line link with the help of from one to three RMS-16 repeaters in leak-proof housings.

      • Two options of remote units’ construction: for indoor installation and outdoor installation in leak-proof housing.

      • Network monitoring system support.

      • Protection of subscriber and line interfaces against lightning and industrial over voltages in accordance with ITU-T K21 and ITU-T K17.

      • Working ambient temperature of remote units in leak-proof housings and RMS-16 repeaters from minus 40 to plus 40°Ñ.

      • Units without leak-proof housings can be installed:

          • into 19” “euro” cabinet;

          into separately shipped 6U cassette (up to 10 units without housings);

          into separately shipped 6U cassette (up to 10 units without housings);

Units ordering information

Base part in designation at the order, specifying determining the purpose, construction and power supply option:

      • “CSP16S” – station unit without leak-proof housing with power supply from DC source 36…72 V, provides remote power supply for outstation unit;

      • "CSP16SR” – station unit without leak-proof housing with power supply from DC source 36…72 V, provides remote power supply for RMS-16 repeaters;

      • "CSP16V” – remote unit without leak-proof housing with power supply from mains voltage 220 VAC or from remote power supply over working cable pair;

      • "CSP16V-G” – remote unit in leak-proof housing with power supply from remote power supply over working cable pair;

      • "CSP16VR” – remote unit without leak-proof housing with power supply from mains voltage 220 VAC? Used for creating line links with RMS-16 repeaters. At order option with power supply from DC voltage source of 36…72 V can be discussed for any constructive option of the unit;

Variable part in designation of the unit at the order:

      • “K” housing-less construction of the units for installation into 6U cassette;

      • “T” – for connecting one or two payphones with local billing with protection of payphone lines;

      • “ASm” – amount of subscriber lines from station side, where “m” is one of the row 0/4/8/12/16;

      • “AKm” – amount of subscriber lines from subscriber side, where “m” is one of the row 0/4/8/12/16;

      • “SLm” – amount of junction lines, where “m” is one of the row 0/4/8;

      • “Eth” – availability of Ethernet 100Base-TX interface.

Example of unit designations at the order:

      • CSP16SR-K-AS8-SL4-Eth – station unit with remote power supply of the repeaters, without housing, for installation into 6U cassette, with modules for 8 subscriber lines, 4 junction lines and with Ethernet 100Base-TX interface;

      • CSP16VR-T-AK8-SL4-Eth – remote unit in non leak-proof housing with power supply from mains 220 VAC with protection of one or two payphone lines with modules for 8 subscriber lines (including connection of one or two payphones), 4 junction lines and Ethernet 100Base-TX interface.
