1307 - SWITCHABLE ATTENUATOR MODULE

The attenuator module provides fast, flexible, highly concentrated level setting for voice and data circuit applications. Provides transmission path design loss adjectives for toll trunks, inter-office trunks, PBX trunks, and local loops. Used when interfacing carrier systems, interfacing carrier with cable, and when attenuation is needed in CCIS conversions. Switchable from 0.0dB to 45.75dB in 0.25dB increments. Each attenuator is a switch selectable 600 ohm balanced square pad.

1309 - SIGNAL PASS ATTENUATOR MODULE

The attenuator module allows the signal to continue thru attenuator panels without internal interference between the receive side and the transmit side. (The units are transparent to the signal.) Used when adjustable switchable attenuation is unnecessary and bypass signals must occur.

1311 - ATTENUATOR BYPASS CARD

The attenuator bypass card is used with one attenuator module (1307, 1309 1317xx, or 1327). Once a module is plugged into the bypass card and then installed into a panel, a switch mounted on the card allows for switching the attenuator module IN or OUT. Panels which accept the card are the 2300x Amplifier Panels and the 1351 and 1352 Channel Interface Panels.

131703 - 3.0dB FIXED ATTENUATOR MODULE
131715 - 15.0dB FIXED ATTENUATOR MODULE

The attenuator module provides fast, flexible, highly concentrated level setting for voice and data circuit applications. Provides transmission path design loss adjectives for toll trunks, inter-office trunks, PBX trunks, and local loops. Used when interfacing carrier systems, interfacing carrier with cable, and when attenuation is needed in CCIS conversions. Each attenuator is a switch selectable 600 ohm balanced square pad.
