XE5617G Pin Configuration

Pin Descriptions

PIN NAME

DESCRIPTION

/DCD

/DCD is an active low output from the modem. This output is controlled by the AT&C

command. In the default condition, AT&C1, /DCD indicates the presence of a valid

carrier signal.

/CTS

/CTS is an active low output from the modem. When hardware flow control is active,

the modem asserts /CTS to indicate that it can accept data from the terminal equipment

on /TXD.

/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.

/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.

/RTS

/RTS is an active low input to the modem. When hardware flow control is active, /RTS

indicates to the modem that the host has data to send.

/DTR

/DTR is an active low input to the modem. The operation of /DTR is controlled by the

AT&D command. As the default, AT&D2, the modem interprets /DTR as an indication

that the Host is ready to communicate, and if /DTR is removed while the modem is on-

line, the modem drops the connection and enters command mode.

XE5617G Pin Descriptions (continued)

PIN NAME

DESCRIPTION

/RXD

/RXD provides the path for received data and modem responses to be sent from the

modem to the host terminal equipment.

/TXD

/TXD provides the path for transmitted data and modem commands to be passed from

the host terminal equipment to the modem.

/RI

The /RI signal reports on the presence of an incoming ring signal. When a ring occurs

at Tip and Ring, the /RI output goes low and toggles with the cadence of the ring signal.

Ground

Ground provides the reference voltage for all host interface signals.

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.

Tip

The Ring and Tip signals provide modem the connection 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 XE5617G will operate regardless of the polarity of this

“Battery” voltage. The “Battery” voltage drives up to 100 milliamps of DC loop current.

UL60950 requires minimum creepage and clearances distances be maintained between

the Tip and Ring traces and all other circuits. Clearance is the shortest distance between

conductive circuits; creepage is the distance between conductive surfaces along the

surface

N/C

No internal connection, To prevent damage in case of voltage surges on the telephone

line, we recommend that nothing be connected to this pin.

Ring

The Ring and Tip signals provide modem the connection 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 be maintained between

the Tip and Ring traces and all other circuits. Clearance is the shortest distance between

conductive points along the surface.

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

XE5617G Connection Data

The XE5617G 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
