NT8X13 — This crosspoint card, used in the NT8X10 Junctored Network,
contains the TS for 2048 input channels and 1024 output channels. Two
pairs of cards are required, one pair for switching from the peripheral input
channels to the junctor output channels on the A-side, and one pair for
switching from the junctor input channels to the peripheral output channels
on the B-side.
NT8X14 — This test code card, used in the NT8X10 Junctored Network,
interfaces the NM with the network control processor (NCP) card for the
insertion and extraction of test code (TC) and for the testing of the digital
pads. The TC is used by the CC or the computing module to check the con-
tinuity of a PCM path. If the TC card does not trace the expected test code,
the location is read by the NCP and sent to the CC or the computing mod-
ule. A card list of suspected faulty card(s) is displayed at the MAP.
NT8X18AA — DS30A C-side Interface Card, located in the SMS-R shelf,
connects to the RSC.
NT8X99 — The LCME Power converter circuit pack provides +5v dc to
the NTBX34 and the two NTBX35s for its own LCM or the SRU of the
SRU, and provides +15v dc to the Line Drawers and has the capability to
power the mate LCM/SCU for power redundancy. This pack also contains
the Ring, ANI and Coin detector/multiplexer circuit, and in addition, has
isolating diodes for serving the Line Drawer voltage needs.
NT9X10AA — The 33-MHz 88100 BRISC CPU card, located in the SN
Computing Module (CM) Processor shelf and the SNSE CM/SLM shelf,
provides a stepped performance increase over the NT9X13 family of pro-
cessors. This processor card can be replaced card-for-card with the
NT9X13 DMS-core processor card, with the exception of a remote termi-
nal interface (RTIF) board. The NT9X10AB BRISC CPU card is currently
supported for use in the Series 60 CM. The NT9X10BA BRISC CPU card
is currently supported for use in the Series 70 CM. It is based on the
Motorola 88110 microprocessor, operated at 60 MHz. The NT9X10BA
behaves as both CPU and memory card. It will contain 256Mbyte of gen-
eral purpose (PS and DS) memory. It is used for Series 70 SN & SNSE
applications.
NT9X12
— The CPU port card, located in the SN Computing Module
(CM) Processor, SLM, and the SNSE CM/SLM shelves, provides a
high-bandwidth communications link between the CPU and message
switch. The transport mediums can be either a DS512 fiber optic link,
with a 40.96 Mbps capacity or DS30 transmission link, with a 2.084 Mbps
capacity. A standard configuration consists of four port cards per system,
with each half of the processor having two port cards in the card slots
immediately adjacent to each processor. The NT9X12AC supersedes the
NT9X12AB CPU port card. It adds parity and fault isolation capabilities to
the transmit and receive buffers located on the card.
NT9X13BB
— This DMS SuperNode processor card, located in the Com-
puting Module (CM) Processor shelf, is a high-perfor- mance microcom-
puter board based on the Motorola MC68020 32-bit microprocessor. The
NT9X13BC uses the E87 version of the 68020 rather than A70, and it uses
the H42 version of the memory access unit. See the NT9X13MA card.
NT9X13CA
— This CPU circuit card is a high-performance microcom-
puter board based on the Motorola MC68020 32-bit microprocessor. Its
primary application is in signaling transfer point (STP) and enhanced net-
work (ENET). It has the potential for other applications that are based on
Supernode hardware.
NT9X13DA/DB — This CPU 20-MHz processor card, primarily located
within the Message Switch (MS), is a high-performance microcomputer
board based on the Motorola MC68020 32-bit microprocessor. It is
intended for general purpose applications as well as special purpose appli-
cations such as the DMS SuperNode.
NT9X13DC
— This CPU 20-MHz processor card is a high-performance
microcomputer board based on the Motorola MC68020 32-bit micropro-
cessor. It uses all 4 Mbytes of available memory.
NT9X13DD and DG — This CPU 20-MHz processor card performs spe-
cial applications in the junctor network (JNET), enhanced network
(ENET), single shelf link peripheral processor (SS LPP), and link interface
module (LIM). The NT9X13DG is an upgrade.
NT9X13FA
— This CPU 20-MHz processor card, located in the ENET
shelf, is a high-performance microcomputer board based on the Motorola
MC68020 32-bit microprocessor.
NT9X13GA — The DMS-core 33-MHz 68030 HPM-based CPU card
high-performance module (HPM)-based CPU card that provides a
real-time performance gain while supporting software compatibility. The
processor card allows a direct card-for-card replacement with the NT9X13
DMS-core processor card.
NT9X13HB — The CPU (68030) 40-MHz processor card provides a
real-time performance gain while supporting software compatibility. The
processor card allows a direct card-for-card replacement with the existing
NT9X13 DMS-core processor card.
NT9X13KA — This 20-MHz MC68020 CPU card, located in the ENET
shelf, is a high-performance microcomputer card that is based on the
Motorola MC68020 32-bit microprocessor.
