Pulse link repeater

In telecommunication, a pulse link repeater (PLR) is a device that interfaces concatenated E&M signal paths.

Note 1: A PLR converts a ground, received from the E lead of one signal path, to -48 Vdc, which is applied to the M lead of the concatenated signal path.

Note 2: In many commercial carrier systems, the channel bank[?] cards or modules have a "PLR" option that permits the direct connection, i.e., concatenation, of E&M signaling paths, without the need for separate PLR equipment.
