In a TX/RX chassis with an internal hybrid the TX and RX ports are combined and fed out through the
middle port. The RX port can be used as an output to send the received signal to an additional device if
required. The TX signal also appears on the TX connector for alignment and testing purposes.
The 106585-4 is identical to the 106585-3 but has a two position terminal block for connecting an
external receive level meter. The 106585-5 is identical to the 106585-4 but has two sets of terminal
block connections. The added terminal block connections can be used to isolate the UHF connectors
and protection circuitry from the internal connections to the hybrid module.
17.8.1.3 TX RF LINE I/O MODULE (106585-6)
The 106585-6, is a TX RF Line I/O module, which provides one UHF connector with a spark-gap
protection device. This I/O can be used in a TX or TX/TX chassis.
17.8.1.4 RX RF LINE I/O MODULE (106585-7)
The 106585-7, is an RX RF Line I/O module, which provides one UHF connector with a spark-gap and
additional protection circuits, as well as a selectable termination impedance (50Ω, 75Ω or none). This
I/O can be used in an RX or RX/RX chassis.
17.8.1.5 TX/RX RF LINE I/O MODULE (106585-8)
The 106585-8 Line I/O module provides four UHF connectors for field connections. Three of the ports
(J5, J6 and J7) have spark gap protection devices and J8 does not since it is only used for local
connections. Port J5 is used for Tx signals, port J7 is used for Rx signals, and port J6 is used for
combined signals. This I/O is normally used in Tx/Rx chassis.
The 106585-8 is used to tie two Tx/Rx chassis to one single line, where one of the Tx/Rx chassis has an
X-hybrid and the other Tx/Rx chassis has a skewed hybrid. TB1 and TB2 are used to gain access to the
RF signals, or to insert line test equipment.
17.8.1.6 TX/RX RF LINE I/O MODULE (106585-9)
The 106585-9 Line I/O module provides four UHF connectors for field connections. Three of the ports
(J5, J6 and J7) have spark gap protection devices and J8 does not since it is only used for local
connections. Port J5 is used for Tx signals, port J7 is used for Rx signals, and port J6 is used for
combined signals. This I/O is normally used in Tx/Rx chassis.
The 106585-9 is used to tie two Tx/Rx chassis to one single line, where one of the Tx/Rx chassis has an
X-hybrid and the other Tx/Rx chassis has a skewed hybrid. The two position terminal block is used to
connect an external receive level meter.
17.8.1.7 TX/TX RF LINE I/O MODULE (106590)
The 106590 is a TX/TX RF Line I/O module. It provides three UHF connectors for field connections.
All three ports have a spark gap protection device. The top port (J5) and the bottom port (J7) are for TX
signals. The middle port is for combining the two TX signals through a hybrid.
17.8.1.8 RX/RX RF LINE I/O MODULE (106605)
The 106605 is an RX/RX RF Line I/O module. It provides two UHF connectors for field connections.
Both ports have spark gap protection devices. The top port (J5) and the bottom port (J7) are for RX
signals. The two position terminal blocks next to J5 and J7 are for connecting an external receive level
meter.
