PPC/PMC-8260/DS1
Connecting a telephone or Ethernet to the RJ-45 connector of the PMC-
8260/DS1-H110-F and SC-F variants causes damage to the telephone, the
PMC module and to attached devices. Therefore, only connect E1/T1/J1 lines
to the RJ-45 connector using a Digital Service Unit / Control Service Unit
(DSU/CSU).
The following connector pinout may be useful to give information on which signal

The PPC/PMC-8260/DS1 offers two user-programmable LEDs L1 and L2 (for lo-
cation see Figure 4 "Front Panels" on page 3-3) which can take the states "off",
"red", "green" and "yellow". At power up, they show the state of the power-up se-
quence. Furthermore, you can control the status of the LEDs with the LED Control
Register (see the "LED Control Register" section on page 5-23).
The following table shows the LED settings during power up:
