K. T1/E1/PRI CARD
10.42 The T1/E1/PRI card, shown on
system that supports T1/ E1 and PRI.
10.43 The T1/E1 board is converted for Primary Rate Interface (PRI) use by adding a feature
PAL on the card. There is no daughter board for PRI.
10.44 The T1/E1/PRI card supports programmable gain control, as described on
However, it also has DIP switches to program gain control for older versions of software, as
described in the installation document shipped with the card. (If the phone system is upgraded
to a version of software that supports programmable gain control, the programmed setting in
the database overrides the settings programmed by the DIP switch.) All trunks, regardless of
the board they are on, have default transmit and receive gains of 0 dB in the database. The pro-
grammable range for the Transmit or Receive gain is -16 to +12 dB.
10.45 The T1/E1/PRI card uses flash memory, in place of EPROMS, to determine the PRI
software version. The PRI software is included on the Inter-Tel edGE Web site and can be
downloaded if necessary.

MANUAL VERSION 11.0 – May 2008
Place the T1/E1/PRI card on a clean, flat, anti-static surface.
NOTE:
T1/E1/PRI cards can be inserted or removed with the system power turned on,
as long as the T1/E1 span is not connected to the card. However, before removing a
T1/E1/PRI card while power is on, first press the make-busy switch on the card and
allow the system to "busy out" the T1/E1 span, then unplug the T1/E1 span from the
connector on the card.
Jumper J14, in the lower right corner of the board, does not need to be installed. How-
ever, if it is, it must be over the bottom two pins, as shown on the next page. (This is the
write-protect jumper. If it is not installed or is over the bottom two pins, the card's
"boot sector" is protected from being overwritten. The boot sector is the card's basic
code that provides flash programming functionality. It does not change from version to
version, but may require future upgrades.)
NOTE:
Jumpers J4 and J5 normally are not used. If required by local telecom [net-
work provider] rules, jumpers over the lower two pins of J4 and the lower two pins of J5
apply frame ground to the transmit and receive ring leads.
Jumpers J10 and J15 select the T1/E1 termination impedance. The setting is generally
country specific. For T1 applications, set it to 100 ohms. For E1, set it to 120 or 75
ohms, depending on the requirements of the local provider. The jumper positions are
indicated on the board and in the figure on the next page.
To convert the card for PRI use, carefully install the PRI PAL in socket U14, see
3-62 on page 3-130. The notch (or small dot in the corner) indicating pin 1 on the PAL
must match the notch of the outline silk-screened on the card. Check to see that the PAL
(part number 827.8877) is seated securely in its socket and that no pins are bent.
Install the T1/E1/PRI card in the equipment chassis. The PRI software is uploaded auto-
matically, as described on the next page.
page 3-130, is compatible with any version of the phone
page 6-257.
