86
vides a 4-wire twisted-pair connection externally.
NT9X86 — The dual-port message controller, with a link paddle board,
provides two serial message communications links to the DMS-bus from a
computing module, an applications processor module, or a file processor
module. It provides up to two high-bandwidth communications links to the
DMS-bus through the message switch and a local time-of-day (TOD) clock
for applications running in a computing module environment, a file proces-
sor, or an applications processor
NT9X87 — This dual-access buffer memory card located within the file
processor (FP) shelf provides a large random-access dual-ported buffer
memory. This memory is used when passing commands to the controllers,
and to hold the data going to and coming from the disk.
NT9X88 — The SCSI interface processor (SIP) paddle board is an integral
part of the file processor (FP) disk and tape drive interface. It provides a
standard small computer system interface (SCSI) port to connect to disk
and tape mass storage devices.
NT9X89
— The FP accesses mass storage devices using a small computer
systems interface (SCSI) bus. The NT9X89AA is an interface between
these storage devices and the SCSI bus.
NT9X90 — The storage device assembly is located in the file processor
(FP) storage device shelf. The NT9X90AA is the hard disk 600 Mbyte
device version, the NT9X90AB the 2.1 Gbyte disk version, and the
NT9X90BA is the 1.2 Gbyte device version.
NT9X91 — This power converter provides regulated and protected output
of +5 V and +12 V to storage devices on SuperNode shelves.
NT9X96
— The link interface shelf (LIS) frame transport bus (F-bus) con-
troller card, NT9X96AA, in conjunction with a NT9X98AA paddle board
(LIS fiber interface), allows the LIS to connect directly to the DMS-bus by
means of a fiber cable.
NT9X98 — The link interface shelf (LIS) fiber interface paddle board pro-
vides a direct link by a fiber cable between the link interface shelf and the
DMS-bus.
Office Hardware Inventory Package (OHIP) Table
(
NTP 297-YYYY-350, Translations Guide
)
Two tables within the switch—OHIP and OHIPBULK—can be used to
keep track of all the in-service and spare hardware inventory (including
HOST and REMOTES). Table OHIP can be used to keep track of all the
in-service and spare hardware inventory, except line cards, while table
OHIPBULK keeps track of all the spare circuit packs and all the line cards
on a quantity basis. Tables OHIP and OHIPBULK are interdependent.
The initial and ongoing datafill of tables OHIP and OHIPBULK is the
responsibility of the operating company.
Ringing Generators
The following ringing generators contain two cards: the 6X38 Ringing
Control Card and the 6X37 Ringing Amplifier card:
6X30AA — Ringing Generator 6X30BA — Japanese market
6X30CA — Ringing Generator 6X30BB — Japanese market
6X30AE — Australian market 6X30DA — DMS-10 in China and the
Australian DMS-100 market
The following ringing generators contain a single card providing the same
functions of the 6X38 and 6X37 as was required with the generators above:
6X30DB — DMS-10 in China and the Australian DMS-100 market
6X30EA — Australia (Small Remote Unit)
6X30AB or FA — United Kingdom (U.K.)
6X30GA — U.K. (SRU)
6X30HA — U.S. & Canada
6X30JA — Japan
Note: For information about setting DIP switches, tolerances for ring-
ing, and ANI and coin voltages, see the NT6X30 Ringing Gen-
erators in NTP 297-8991-805, Hardware Description Manuals.
Also, see NTP 297-1001-131, Ringing System Description and
Installation documentation (Method 2231 within Module 22).
