3.2.3 EXTENDING A LANDLINE (TAIL CIRCUIT)
Integra-TR may be used to extend a landline circuit (giving access to difficult locations, etc.).
This type of connection is called a “tail circuit” and is shown in Figure 11. The tail circuit assembly may be used in any of the
network types described in the preceding sections.

Note: The line modems should be full-duplex units.

Some point-to-point FDX landline modems or line drivers may require the use of DOX mode and an alternate pinout for
DTR, DCD, CTS and RTS as shown in Figure 13.
