MICRO SEVEN, INC.® MODEL
CS10 TELEPHONE CABLE SIMULATOR SIMULATES A TWISTED COPPER PAIR OF CABLE FOR
DIGITAL AND ANALOG TELEPHONE LINES FOR TESTING DSL AND ANALOG TELEPHONY FOR
ISDN AND DSL APPLICATION
INTRODUCTION
Micro Seven Model CS10, Telephone Cable Simulator,
provides simulation of a twisted copper pair of cable for ADSL application
where a single twisted copper pair cable is used for both analog telephone and
DSL modems. The CS10 simulates cable resistance, capacitance, and inductance
for maximum 7.5 (CS10) or 15 kilometers (CS10-1) of telephone lines depending
on its configuration. It also provides test set up for cross-talk path from
adjacent cable or earth ground to simulated telephone lines. The CS10 front
panel contains four RJ11 connectors including digital input (ATU-C, ADSL
transceiver unit, central office end), digital output (ATU-R, ADSL transceiver
unit, remote terminal end), analog input (PSTN), and analog output (POTS).
Splitters consisting of inductors and capacitors are included in CS10 for
separating digital and analog lines. Programming of cable distance is
accomplished by RS232C interface. Programmed parameters are stored in
non-volatile memory inside CS10. Programmed cable parameters do not change even
after power to CS10 is turned off. After CS10 programming is completed, CS10
may be carried in a case for field testing of telephone lines and/or
telecommunication equipment. Connecting real telephone lines to CS10 for
telephone cable simulation must be conducted with power cable and RS232C
interface cable removed to avoid possible high voltage surge from telephone
line onto equipment and operators. CS10 operates also with DC input power
source by using an optional car battery adapter. Telephone line simulator with
Micro Seven’s LS15-C1 or LS100/LS200 is connected to Analog Input RJ11 to
provide analog central office function. Control software is provided with
RS232C interface to PC. A carrying case, Car Battery Adapter, International
AC/DC adapter, and CO simulator with LS15-C1 are available as options. CS10-2
provides 7.5km telephone cable simulation for 4-wire circuit.

SPECIFICATIONS
It simulates cable resistance, inductance,
and capacitance for 0-7.5 km (CS10), or 0-15 km (CS10-1) for 1 km increment for
26 AWG single twisted copper pair. Reference: ANSI T1.413-1995, Network and
Customer Installation Interfaces-Asymmetric Digital Subscriber Line (ADSL)
Metallic Interface, ANSI T1.601-1992, ISDN Basic Access Interface for Use on
Metallic Loops for Application on the Network Side of the LT (Layer 1
Specification)
Cable characteristics: balanced, symmetrical
networks
Danger: Connecting real telephone
lines to CS10-1H for telephone cable simulation must be conducted with power
cable and RS232C interface cable removed to avoid possible high voltage surge
on equipment and operators.
Maximum DC voltage: 250V across tip and ring
Maximum DC current: 100 mA
Maximum AC voltage: 10dBm into 600 ohms
High voltage isolation between pins in
telephone line connector and case or AC/DC power adapter:
3kV peak when power and RS232C cables are
removed.
200V peak when power and RS232C cables are
connected.
All programmed parameters including
resistance and capacitance remain unchanged after power is turned off.
