The American Fibertek 89C-GE Series are designed to interface with the
Commend digital series intercom systems. The 89C-GE Series provides
bi-directional transmission of an ISDN line rate data signal over one
multimode or single mode optical fiber. The 89C-GE modules can
provide 28 Vdc to the Commend intercom / module stations.
Designed to be completely transparent, the system requires no field
adjustments at installation or additional maintenance thereafter.
Diagnostic indicators provide a quick visual indication of system status.
Equipment may be ordered as stand alone modules or rack cards that
are mounted in an SR-20/2 American Fibertek Card Cage.
