Installing the I/O Card
The 8-port I/O card provides the APM with CPE connections. The I/O card inserts
directly behind the APM that it supports. Slot numbers are identical to facilitate correct
installation.
1. Remove the I/O card from the shipping box. Handle only by the top
and bottom edges to avoid damaging the card.
2. At the rear of the housing, align the I/O card with the upper and lower
tracks of the slot. Push gently towards the midplane until it stops and
you cannot push the card any further.

! WARNING:
In order to maintain compliance with Part 68, FCC Rules and Industry
Canada’s CS-03 Specification, the transmit gain settings associated with the
E&M Voice APM must be set to ensure that:
The absolute signal power of the encoded analog signals, other than live
voice and network control signaling, will not exceed –12 dBm when
averaged over any 3-second interval.
For network control signals (such as DTMF), the level will not exceed
–3 dBm.
The E&M voice lines are to be connected to locally attached equipment only.
Under no circumstances should voice lines be used on exposed (outside)
plant lines.
See the Model 916x T1 CSU/DSU Access Unit and T1 Mux Technical Reference
(Document No. 9161-A2-GH30) for configuring for a voice application.
Installing the Ferrite Choke
A ferrite choke is supplied with the E&M Analog Voice APM. This ferrite choke must be
installed on the cable when you are using this APM in a 5-slot housing.
CAUTION:
All supplied ferrite chokes
must be installed following
these instructions to ensure
compliance with regulatory
rules.
1. Open the ferrite choke and
place it around the cable as
close to the cable connector
as possible. The Ferrite choke
must be installed on the cable
that attaches directly to the
E&M Analog Voice APM when
installed in a 5-slot housing.

2. Close the two halves around
the cable and snap the choke
shut, pressing down on the
plastic latch to secure it in
place.
