Line cards
All line cards except the LTI can be provisioned in any order in the 16 slots for
the IPE module. The LTI card requires two consecutive slots. All cards within
the IPE are simplex:
•
Digital Line Card (DLC), NT8D02
•
Analog Message Waiting Line Card (MLC), NT8D09
•
Analog Line Card (ALC), NT8D03
•
Line Side T-1 Interface Line Card (LTI), NT5D11
•
Meridian Integrated Conference Bridge (MICBII)
•
Meridian HomeOffice II (MHO II Release 2), NTQR02AA
Digital Line Card (NT8D02)
The Digital Line Card (DLC) interfaces to Integrated Voice and Data (IVD)
digital terminals. These terminals include the M2000, M3000 series, and their
respective data options. A DLC inserts into any line card slot on the IPE shelf
and can interface with a maximum of 16 digital sets for each DLC card for a
total of 32 ports.
The DLC is equipped with an Intel 8051-type microprocessor that performs
functions such as control of card operation, card identification, self-test, status
reporting to the controller, and maintenance diagnostics. The DLC interfaces
