DESCRIPTION
1
Tip
The Ring and Tip signals connect the modem to the telephone line. FCC Part 68 Rules
require a 1500 volt isolation barrier between the telephone line and all other circuits.
This isolation must be preserved throughout the system.
The telephone company places a DC “Battery” voltage across Tip and Ring on public
switched telephone lines. The XE5617H operates regardless of the polarity of this voltage.
The “Battery” voltage drives up to 100 milliampere of DC loop current.
UL60950 requires minimum creepage and clearances distances between the Tip and
Ring and all other circuits. Clearance is the shortest distance between conductive circuits;
creepage is the distance between conductive points along the surface
2
Ring
The Ring and Tip signals connect the modem to the telephone line. FCC Part 68 Rules
require a 1500 volt isolation barrier between the telephone line and all other circuits.
This isolation must be preserved throughout the system.
UL60950 requires minimum creepage and clearances distances between the Tip and
Ring and all other circuits. Clearance is the shortest distance between conductive circuits;
creepage is the distance between conductive points along the surface.
3
/DSR
/DSR is an active low output from the modem. The /DSR signal typically indicates that
the modem has established a communications link. The AT&S command determines
the operation of the /DSR signal.

PIN NAME
DESCRIPTION
4
/DCD
/DCD is an active low output from the modem. /DCD normally indicates that the mo-
dem has detected a valid carrier signal from the remote modem. The AT&C command
controls when the XE5617H asserts /DCD.
5
/DTR
/DTR is an active low input to the modem. An active /DTR signals traditionally
indicates that the terminal is available for communications. The AT&D command
determines how the modem interprets activity on /DTR.
6
/RI
The /RI signal reports on the presence of an incoming ring signal. When a ring occurs
across Tip and Ring, the /RI output goes low and toggles with the cadence of the ring
signal.
7
SPKR
SPKR provides a Pulse Width Modulated version of the signal on Tip and Ring allowing
connection of a speaker to the modem to monitor modem operations. The signal on
SPKR is controlled by the ATL and ATM commands.
8
Ground
Ground provides the reference voltage for all host interface signals.
9
/TXD
/TXD provides the path for transmitted data and modem commands to be passed from
the host controller to the modem.
10
/RXD
/RXD provides the path for received data and modem responses to be sent from the
modem to the host controller.
11
/RESET
/RESET is an active low input which initiates a modem hardware reset. /RESET must
be active for a minimum of 100 milliseconds for a proper modem reset sequence. No
external reset is required; if none is used the RESET signal should be left open.
12
/CTS
/CTS is an active low output from the modem. When hardware flow control is set, the
modem asserts /CTS to indicate that it can accept data from the terminal equipment on
/TXD.
13
N/C
No Connection; this pin should remain unconnected.
14
VCC
VCC provides 3.3 volt power to the modem.
15
/RTS
/RTS is an active low input to the modem. When hardware flow control is set, an active
/RTS indicates to the modem that the host has data to send.
16, 17
N/C
These pins are provided only for mechanical stability. These pins must remain
unconnected.

Notes:
1 Capacitors, C1 and C2, may be required for EMI filtering in your system. Without these components
you may experience unintended radiation when the telephone cable is attached. C1 and C2 are high-
voltage capacitors. We recommend the Novocap ES2211N681K502NXTM . This 680 pfd, 5000 volt
capacitor will direct the high frequency harmonics to the system ground.
2. F1 is a positive thermal coefficient (PTC) device which protects the modem from excessive current
flow. These devices are required for your system to pass UL60950. Fuses may be used in place of the
PTC’s

XE5617H Connection Data
The XE5617H reports data on the current connection in response to the ATI11 command. Because many
of the reported parameters require an active connection, this command is best utilized from the on-line
command mode accessed with the escape sequence. The items shown in italics are only valid during an
active call.
The Connection Report is presented in two pages. The first page will be displayed on receipt of the ATI11
command. To move to the second page of the report hit any key. The table below describes the

FCC Instructions
The XE5617H complies with Part 68 of the FCC Rules and Regulations. With each device shipped, there
is a label which contains the FCC Registration Number. The FCC Registration number incorporates the
Model Number, Manufacturer Identifier, Product Type identifier and Ringer Equivalence Number (REN)
for this product. You must, upon request, provide this information to your telephone company. The format
of the FCC Registration Number TBD
The mounting of this device in the final assembly must be made in such a manner as to preserve the high
voltage protection between the TIP/RING Connection and the rest of the system. Typically, this may be
accomplished by maintaining a minimum spacing 100 mils between the TIP/RING Traces to the RJ-11C
Jack and low voltage portion of the system. No additional circuitry may be attached between TIP/RING
and the telephone line connection, unless specifically allowed in the rules.
The REN is useful to determine the quantity of devices you may connect to a telephone line and still have
all of these devices ring when the number is called. In most, but not all areas, the sum of the RENs of all
devices connected to one line should not exceed five (5.0). To be certain of the number of devices you
may connect to the line, as determined by the REN, you should contact the local telephone company to
determine the maximum REN for you calling area.
If your system causes harm to the telephone network, the telephone company may discontinue service
temporarily. If possible, they will notify you in advance. If advance notification is not practical, you will be
notified as soon as possible.
Your telephone company may make changes in its facilities, equipment, operations or procedures that
could affect proper functioning of your equipment. If they do, you will be notified in advance to give you
an opportunity to maintain uninterrupted telephone service.
If you experience trouble with this device, please contact XECOM at (408) 942-2210 for information on
obtaining service or repairs. The telephone company may ask you to disconnect this device from the
network until the problem has been corrected or until you are sure that the device is not malfunctioning.
