56K ADTRAN Total Reach^® Plug-in Isolator Card

The 56K ADTRAN Total Reach® Plug-in Isolator Card provides high voltage isolation between an ISDN line or a Total Reach DDS circuit and the network termination (NT) equipment at the substation.

The card can be powered from either -24 Vdc or -48 Vdc.

Applications

• Regular ISDN line with or without battery feed
• Total Reach ISDN from Adtran
• Total Reach DDS from Adtran
• Two-wire AC circuit with 100 to 200Ω impedance (by setting battery feed to disable)

Features

• The card meets ANSI T1.601-1992, RC9042A, FCC part 15, subpart B and UL60950
• The card can operate with or without battery feed by a customer selectable option
• If the battery feed is used, interruption of current on the CO side will be reflected on the Station side. This permits supervisory control, as specified in ANSI T1.601-1992
• The current on the CO side can be set to 2 mA or 20 mA using a jumper setting
• The battery feed on the Station side can be set to -100 Vdc (positive on Tip), -50 Vdc (positive on Tip), -130 Vdc (positive on Tip) or -65 Vdc (positive on Tip). The battery can be grounded or set to a floating condition
• The card is powered from either the -24 Vdc or -48 Vdc output of a Teleline Isolator plug-in power supply
