NT9X26DA, DB, or DC — This reduced instruction set computer
(BRISC) remote terminal interface (RTIF) paddle board incorporates the
features of all existing RTIF cards. It also provides CPU firmware
(CPUFW) PROM residence for the NT9X10AA and the NT9X13MA CPU
cards. This card provides a reset system for monitoring and controlling the
subsystems of the DMS-100 SuperNode and related subsystems. The
NT9X26DC is available to support mixed memory configuration available
in NA004.
NT9X26EA — A BRISC RTIF paddle board that contains firmware to
support the NT9X10AB BRISC CPU card on Series 60 SN and SNSE
switches or the NT9X10BA BRISC CPU card on Series 70 SN and SNSE
switches.
NT9X27AA & BA — The CM bus extender paddle board extends the
peripheral bus (P-bus) from the NT9X06AA (computing module (CM)
processor shelf), used for housing CPU and memory, to the NT9X07AA
(CM extension shelf), used for housing the system load unit (SLU). An
NT9X27BA card (CM extension shelf bus extender) installed in the exten-
sion shelf receives the signals from the NT9X27AA and buffers them onto
the extension shelf backplane. Two NT9X27AAs are required on a CM
processor shelf for each installed extension shelf.
NT9X30AA — This is a dc-to-dc +5V 86-A power converter.
NT9X30AB — A global dc-to-dc +5V 86-A power converter.
NT9X31AA
— This is a dc-to-dc -5V 20-A power converter.
NT9X31AB — A global dc-to-dc -5V 20-A power converter.
NT9X32
— The DMS-bus load paddle board, located in the SN message
switch shelf, is designed for the DMS-bus environment. The card ensures a
consistent load distribution on the main clock and frame pulse signals driv-
ing the shelf, independent of card population or shelf type (master or exten-
sion). This results in a significant improvement in signal edge integrity,
noise margin, and duty
cycle on these key signals.
NT9X35BA or CA — The Enhanced Network (ENET) 128K
crosspoint card performs the nonblocking switching function.
NT9X36BA — The ENET message clock card provides two DS512 mes-
sage links between the ENET shelf processor and the message switch. It
also provides the clocks and timing signals required by the shelf. The card
and its associated paddle board NT9X40BA (ENET+ quad fiber paddle
board) provide two DS512 communication links between the ENET shelf
and the duplicated message switches (one link per plane).
NT9X40BA — The ENET+ quad fiber paddle board is used to receive,
transmit, and repeat four DS512 fiber links.
NT9X40BB
is an enhanced version of the BA card and utilizes the latest
version of the DS512 treatment receiver controller (DTRC).
NT9X40DA — This ENET paddle board uses four hard-clad silica (HCS)
fibers operating at 650 nm wavelength to provide 2048 channels to the
ENET XPT cards. The SPM IF to ENET uses this card.
NT9X41BA — The 16-port DS30 paddle board links DS30 peripherals to
the enhanced network through twisted-pair copper cables.
NT9X44AD
— This is the SLM III Unit (CM load greater than 350 MB).
The SLM-III’s 1-gig drive, which replaces the SLM II 600-megabyte disk
drive, NT9X44AB which is MD’d. The NT9X44AC 1A SLM is also MD.
The NT9X44AA, AB, and AC SLM are at end-of-life (EOL) on 5/02.
NT9X45BA
— This three-DS512 link and 16-DS30 port paddle board,
located within the SNSE ENET shelf, is a combination ENET paddle board
equivalent to three quarters of the functionality of NT9X40BA, plus the
full capacity of NT9X41BA.
NT9X46AA — This parallel computing module (CM) port interface pad-
dle board operates as a pair with one paddle board mounted behind an
NT9X12 CPU port card and the other mounted behind an NT9X4402 sys-
tem load module (SLM) controller. An interconnect cable joins the two
paddle boards.
NT9X47AA
— This +12V power converter provides power to the
NT9X44 system load module (SLM). The card interfaces with DMS-100
alarm circuits using the NT9X03 frame supervisory panel (FSP). The
NT9X47AB is the 60V input global version.
NT9X49BA — This message switch (MS) transaction bus (T-bus) termi-
nator card’s primary function is to provide bus termination on the T-bus.
The NT9X49BA also houses T-bus shelf arbitration logic and a set of buff-
ers for the system clocks.
NT9X49CA — This SuperNode message switch (MS) processor-bus
(P-bus) terminator circuit card provides termination for MS backplane
tracks used by the message switch processor (MSP). It also provides an
interface to the P-bus extender paddle board (PB) (NT9X48AA) and a
time-out on the MS transaction bus (T-bus).
NT9X49CB — This is a logic analyzer that traces transaction bus (T-bus)
messages. It is configured by the SN message switch processor. It also
serves as a T-bus activity monitor with programmable threshold detection,
and as a processor bus (P-bus) terminator, performing the same functions
as NT9X49CA (MS P-bus term.).
