HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
compatibility with existing PMC devices is optimized. The resulting register
organization splits into sections: Master configuration registers, 28 sets of T1/E1
Framer registers, DS3 M13 multiplexing registers and SBI registers.
On power up reset the TECT3 defaults to 28 T1 framers multiplexed into the M13
multiplexer using the DS3 M23 multiplex format. For proper operation some
register configuration is necessary. System side access defaults to the SBI bus
without any tributaries enabled which will leave the SBI Drop bus tristated. By
default interrupts will not be enabled, automatic alarm generation is disabled, a
dual rail DS3 LIU interface is expected and an external transmit reference clock
is required.
