• Manufacturer Part Number: cx29610
• Description: Optiphytm - M622 Sts-12/4x Sts-3 Sonet/sdh Multiplexer
• Manufacturer: Mindspeed Technologies

–Continued from Front–
is provided for access to control and
status registers. This interface
provides direct conectivity to the
Mindspeed EBUS and the Motorola
MPC860 microprocessor interfaces.
A full complement of status
monitoring, alarm indications, and
error counters is provided with
maskable interrupts for all status
indications.
CX29503 Mindspeed’s Broadband
Access Multiplexer (BAM) which is a
highly integrated
STS-1/DS3/E3/DS1/E1/VT1.5
Mapper/Framer. This chipset
provides multiplexing solutions from
T1/E1 up through STS-12 through
either PDH, SONET, or SDH
hierarchies.
