Digital Framer Mode
T1 mode
Setting bit 4 in the Configuration Control Word
(address 10H of Master Control Page 2) disables the
LIU and converts the MT9074 into a digital T1
transceiver.
The
digital
backplane maps into transmit and receive digital
1.544 Mb/s streams. The 1.544 Mb/s transmit
streams may be formatted for single phase NRZ (by
setting bit 7 of the LIU Control Word - Master Page 1
high) or two phase NRZ. The data rate conversion
(between 2.048 Mb/s and 1.544 Mb/s) is done within
the MT9074. The transmit 1.544 MHz clock is
internally generated from a PLL that locks onto the
input C4b clock. This clock is then output on pin
E1.5o (PLCC pin 44 - QFP pin 32). The digital 1.544
Mb/s transmit data is output on pins TXA and TXB
(PLCC pins 37,38 - QFP pins 18,19) with the rising
edge of C1.5o. Receive digital data is clocked in on
pins RRING and RTIP. This data is clocked in with
the rising edge of the input 1.544 Mhz clock S/FR/
E1.5i (PLCC pin 66, QFP pin 63). Coding is optional
under software control.
