| 4201-00 and 4202-00 Conference Bridges |
|
The 4201-00 provides four bridge
circuits and the 4202-00 provides six bridge circuits. Each port receives VF or data
signals from all other ports of the bridge and transmits signals to all other ports.

4201-00 Four-Wire,
Four-Way Conference Bridge
|
|
4202-00 Four-Wire, Six-Way
Conference Bridge
|
- Used with voice or data up to 9.6 Kbps
- Front-panel accessible RCV CAL (receive
calibration) and XMT CAL (transmit calibration) jacks for simplified alignment
- Selectable -7 dB (receive) and -16 dB
(transmit) pads for each bridge circuit allows proper levels to carrier facilities
- 0 dB loss bridge with an adjustable gain of
-10 to +22 dB (receive-to-transmit)
- Powered from any input voltage between -22
and -55 Vdc
- SX (Simplex) leads for each transmit and
receive port

| 4204-03 Master/Slave & 4204-11
Auxiliary Bridges |
|
The 4204-03 bridge provides
distribution from a four-wire master port to four four-wire slave ports. The 4204-11
bridge is used with the 4204-03 to provide five additional ports.

4204-11 Auxiliary Bridge
|
- All master and slave ports are provided with
transformer isolation
- Each port has front-panel bantam test jack
and derives an SX signaling lead
- Master port provides impedance of 150, 600
or 1200 ohms with strapping options
- Slave ports provide impedance of 600 or 900
ohms with strapping options
- 4204-03 has loopback capability
- When optioned on the 4204-03, sealing
current may be applied via the SX leads of the XMT and RCV master ports
