DS0, NxDS0, T1, E1, VT1.5, VT2, DS3
and E3 granular quad SBI to serial
SBI336S time slot interchange.
DS0, NxDS0, T1, E1, VT1.5, VT2, DS3
and E3 granular SBI336 to serial
SBI336S time slot interchange.
VT1.5, VT2, STS-1 quad 19.44MHz
TelecomBus to serial TelecomBus
switch. Requires J1 byte alignment.
VT1.5, VT2, STS-1 77.76MHz
TelecomBus to serial TelecomBus
switch. Requires J1 byte alignment.
With the Narrowband Switch Element,
PM8620 NSE-20G, the SBS can be
used to implement a switch fabric
scaleable to 20Gb/s.
With the Narrowband Switch Element,
PM8621 NSE-8G, the SBS can be
used to implement a switch fabric
scaleable to 8Gb/s.
Integrates two independent DS0
granularity Time Slot Interchange
Switches (full duplex).
Nominal latency through the SBS in
DS0 mode is 125
S. Channel
Associated Signaling (CAS) latency
through the SBS in DS0 mode is two
T1 multiframes (6 ms) or two E1
multiframes (4 ms).
In TelecomBus mode or SBI mode
without DS0 level switching nominal
latency through the SBS is <16
S.
The Time Slot Interchange Switch
permits any receive or incoming byte
from an input tributary to be mapped to
any outgoing or transmit byte,
respectively, on the associated output
tributary.
Supports working and protect serial
SBI336 or TelecomBus links to support
a redundant switch fabric architecture.
Encodes and decodes byte wide SBI
bus and SBI336 bus control signals for
all SBI supported link types and clock
modes for transport over the serial
SBI336S interface.
Encodes data from the Incoming SBI
bus or TelecomBus stream to working
and protect 777.6Mbps LVDS serial
links with 8B/10B-based encoding.
Decodes data from working and
protect 777.6MHz LVDS serial links
with 8B/10B-based encoding to the
Outgoing SBI bus or TelecomBus
stream.
In SBI mode, switches Channel
Associated Signaling bits, CAS, with all
DS0 data.
Uses 8B/10B-based line coding
protocol on the serial links to provide
transition density guarantee and DC
balance and to offer a greater control
character vocabulary than the
standard 8B/10B protocol.
Provides optional PRBS generation for
each LVDS serial data link for off-line
link verification. PRBS can be
processed with minimum STS-1
granularity.
Provides hardware and software
control to coordinate the connection
mapping of the local device, peer SBS
devices and companion NSE switch
devices.

Preliminary
PM8610 SBS
Can communicate with PMC's NSE
switch devices over an in-band
communications channel in the LVDS
links. This channel includes
mechanisms for central switch fabric
control and configuration.
Derives all internal timing from a single
77.76 MHz system clock and a system
frame pulse.
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 16-bit microprocessor bus
interface for configuration, control and
status monitoring.
