Line Controller Local Area Network Interface. 7The line controller local area
network (LCLAN) interface allows the SYSCTL circuit pack to communicate with
the Line Controller (LNCTL) circuit packs. In the FT-2000 OC-48 Repeater Bay,
the SYSCTL circuit pack communicates directly with the board controllers on the
individual circuit packs. The LNCTL circuit pack is not required for the FT-2000
OC-48 Repeater Bay.
Overhead Access Local Area Network Interface. 7The overhead access local area
network (OALAN) interface allows the SYSCTL circuit pack to communicate with
the Overhead Controller - Terminal [OHCTL (TERM)] and Overhead Controller -
Tributary (TOHCTL) (Release 6 and later) circuit pack.
