Features
The PM8610 SBI336 Bus Serializer (SBS) is a:
Can be used with the Narrowband Switch Elements, NSE-20G to implement a DS0
granularity SBI Memory:Space:Memory switch scalable to 20 Gbit/s and the NSE-8G to
implement a switch scalable to 8 Gbit/s. In TelecomBus mode, can implement a 20 Gbit/s
VT1.5/VT2 granularity Memory:Space:Memory switch.
Integrates two independent DS0 granularity Memory Switches. One switch is placed
between the incoming 77.76 MHz byte wide SBI336 bus (or quad multiplexed 19.44 MHz
SBI buses) and the transmit working and protect Serial SBI336S link (or the 77.76 MHz byte
wide transmit SBI336 bus). The transmit working and protect links transmit the same data.
The other switch is placed between the receive working or protect Serial SBI336S link (or the
77.76 MHz byte wide receive SBI336 bus) and the outgoing 77.76 MHz byte wide SBI336
bus (or quad multiplexed 19.44 MHz SBI buses).
Provides 125 µS nominal latency in DS0 mode. Channel Associated Signaling (CAS) latency
through the SBS in DS0 mode is two T1 multiframes (6 mS) or two E1 multiframes (4 mS).
Provides less than 16 µS nominal latency in TelecomBus mode or SBI mode without DS0
level switching.
Scalable Bandwidth Interconnect (SBI) converter and Time Division Multiplexer (TDM)
SBI switch.
Quad byte-wide 19.44 MHz SBI bus to 777.6 MHz serial SBI336S converter.
Byte-wide 77.76 MHz SBI336 bus to 777.6 MHz serial SBI336S converter.
DS0, NxDS0, T1, E1, TVT1.5, TVT2, DS3 and E3 granular quad SBI to serial SBI336S
switch. Supports subrate link switching with the restriction that subrate links must be
symmetric in both the transmit and receive directions.
DS0, NxDS0, T1, E1, TVT1.5, TVT2, DS3 and E3 granular SBI336 to serial SBI336S
switch. Supports subrate link switching with the restriction that subrate links must be
symmetric in both the transmit and receive directions.
Note: The byte-wide 77.76 MHz SBI336 bus interface can be used instead of the serial
SBI336S interface. All converter and switch capabilities can be used with the byte-wide
SBI interface.
VT channelized TelecomBus to TelecomBus converter and TDM switch. This requires
the telecombus J1 byte to be in a fixed location corresponding to a value of 0 or 522 that
is immediately following the C1 octets.
Quad byte-wide 19.44 MHz TelecomBus to serial 777.6 MHz TelecomBus converter.
Byte-wide 77.76 MHz TelecomBus to serial 777.6 MHz TelecomBus converter.
VT1.5, VT2, STS-1 quad 19.44 MHz TelecomBus to serial TelecomBus switch.
VT1.5, VT2, STS-1 77.76 MHz TelecomBus to serial TelecomBus switch.
Note: The byte-wide 77.76 MHz TelecomBus interface can be used instead of the serial
TelecomBus interface. All converter and switch capabilities can be used with the byte-
wide TelecomBus interface.
