44. Pulse form restorer TD-1218( )/G low speed pulse restorer (LSPR) is a
member of the DGM family.
It is used to regenerate the cable signal at
intervals of 1.6 kilometers (1 mile) in coaxial cable CX-11230A/G. The LSPR
is a two-way unit which detects and renews booster signals at 2304 kb/s. It
carries orderwire circuits and will provide loading and access to the
orderwire signal in conjunction with the cable orderwire unit (COU).
