There are two E1/T1/J1 framers assembled. They can be accessed from the 60x
bus.

Note: The framers operating in E1 or T1 mode are compliant to the ITU
G.703 standard. The E1 or T1 line interface transmit signal strongly depends
on the cable length and the resulting signal attenuation. When using a long ca-
ble, the pulse must be stronger than when using short cables. The pulse shape
is programmable via framer registers and can easily be adapted to the user's
application. For a detailed description refer to the PMC-Sierra PM4351 data
sheets.
The E1/T1/J1 signal lines are routed to the two front panel connectors. The trans-
formers for galvanic decoupling and suppressor diodes for primary and secondary
line interface protection are implemented. The front panel line interfaces do not
support long haul T1. For the front panel connector pinout see Figure 6 "Front Pan-
el RJ-45 Interface Connector Pinout"page 3-5.
The PPC/PMC-8260/DS1 provides an LED Control register to control the front
panel LEDs.
