OVERVIEW
The PM8620 NSE-20G is a monolithic
CMOS integrated circuit that performs
DS0 and above granularity Space (cross
bar ) switching on 32 full duplex STS-12
streams.
The device provides 20Gb/s (258,048
DS0s, 10,752 T1s/VT1.5s, 8064
E1s/VT2s, 384 DS3s/E3s) switching.
The NSE-20G can be combined in appli-
cations with the PM5372 TSE and
PM5310 TBS devices from the PMC
CHESS product family and with the
PM8610 SBS and PM8611 SBSLITE.
FEATURES
Supports 32 STS-12 equivalent serial
ports via 777.6MHz, 8B/10B encoded
LVDS links. Each port can be either
Serial TelecomBus or Serial SBI336S.
In SBI mode, switches DS0 or NxDS0
for all T1 and E1 tributaries and
aggregate columns for switching T1,
E1, VT1.5, VT2, DS3 and E3
tributaries.
The NSE-20G can be used with the
companion SBS devices to implement
a switch fabric scaleable to 20Gb/s.
In TelecomBus, switches VT1.5, VT2,
or STS-1 tributaries.
Supports switching of arbitrary non-
standard octet aggregates.
Supports unicast, multicast, and
broadcast for all switching modes.
Supports full-duplex, in-band
communication channels from the NSE
to each SBS or SBSLITE device.
These channels can be used to
initialize and control the SBS's for
fabric monitoring and maintenance.
Supports "1+1" or "1:n" fabric
redundancy in conjunction with the
SBS or SBSLITE devices.
Supports two sets of switch settings
and a controlled method of changing
settings on STS-12 frame boundaries.
PHYSICAL CHARACTERISTICS
Supports an IEEE P1149.1 JTAG test
port.
Provides 32-bit microprocessor bus
interface for configuration, control and
status monitoring.
