XE3314B
June 2000
Low-Cost, Embeddable 33,600 BPS Modem Module
Description
Xecom's XE3314B is a complete, low-cost 33,600 bps
modem in a single component. The XE3314B includes a
transferrable FCC Part 68 Registration and is a UL1950
recognized component.
The XE3314B is a complete modem and includes the
DAA. XE3314B users do not need to add RAM, ROM,
Crystals, transformers, or switches to complete the
modem design. The user only needs to provide the TTL
level, serial interface and the telephone jack.
Features
* FCC Part 68 Registration transferrable to customer’s
system
* UL1950 Recognized Component
* Small Size: 2.75 inches by 1.38" by 0.42"
* Modem Control and Configuration through industry
standard AT Commands.
* Modem Protocols: V.34bis, V.34, V.32bis, V.32,
V.22bis, V.22, V.21, Bell 212A and 103
The XE3314B is a full-featured modem. Besides 33.6
Kbps data transfer, the XE3314B supports data compres-
sion, error correction and fax transfer. The XE3314B
also includes NVRAM for permanent storage of the
modem configuration.
The XE3314B is pin compatible with Xecom's XE1414B
modem. This family of modems permits a simple
upgrade path from 14400 bps to 33,600 bps.
* Fax Protocols: V.17, V.29, V.27ter, and V.21 channel 2
* Error Correction; V.42, MNP2-4 and MNP10
* Data Compression; V.42bis and MNP5 provides a
maximum effective data rate of 133,400 bps.
* Pin compatible with Xecom's XE1414B, XE1414C,
XE3314C and XE5614C.

XE3314B AT Commands (continued)
List of Commands
An asterisk indicates the default setting of the command for the
XE3314B. The default setting may be different for the
European models.
A - Answer Command - ATA forces the modem to immedi-
ately go off-hook and begin transmitting the answer tone se-
quence.
Bn - Select Communications Standard - ATBn selects the
modulation scheme used for connections below 2400 bits per
second
n=0 Selects CCITT standards
n=1 Selects Bell standards*
D - Dial Command - Below are the characters accepted in a
dialing command.
0-9, #, * =
Dialing Digits
L = Re-dial last number
P = Pulse dial
T = Tone dial
S=n = Dial stored number
W = Wait for dial tone
^ = Toggles state of calling tone
, = Pause for the duration of S8
@ = Wait for silence
! = Switch hook flash
; = Return to the command state
En - Command Echo - ATEn determines whether commands
will be echoed back to the host.
n=0 Do not echo commands
n=1 Enable command echo*
Hn - Switch Hook Control - ATHn opens and closes the
modem's hook switch.
n=0 Switch hook relay opens
n=1 The switch hook relay closes
In - Modem Identification - ATIn Identifies the version of
the modem.
Ln - Speaker Volume - ATLn sets the amplitude of the
modem's audio output.
n=0 Lowest speaker volume
n=1 Low speaker volume*
n=2 Moderate speaker volume
n=3 High speaker volume
Mn - Speaker Activity - ATMn determines when the
modem's audio output is active.
n=0 Speaker off
n=1 Speaker on until carrier received*
n=2 Speaker remains on
n=3 Speaker off during dialing, on until carrier
Nn - Data Rate - ATNn selects whether or not the modem
will negotiate a lower data link speed.
n=0 Handshake only at DTE rate
n=1 Negotiate highest common speed*
On - On Line - ATOn switches the modem from the com-
mand mode to the data mode.
n=0 Return On Line with no retrain*
n=1 Initiate retrain returning On Line.
Qn - Responses - ATQn determines if the modem will issue
responses.
n=0 Send responses*
n=1 No Responses
Sr? - Interrogate Register - ATSr? requests the current
value in register Sr.
Sr=n - Set Register Value - ATsr=n sets the value of register
Sr to n.
Vn - Result Codes - ATVn sets the modem to issue Numeric
or Full Word result codes .
n=0 Numeric Result Codes
n=1 English Word Result Codes*
Wn - Connect Message Rate - ATWn determines whether
the data rate reported in the Connect response is the host data
rate, the link data rate or whether both are provide along with
the error control and data compression protocols negotiated.
n=0 Send "CONNECT" at DTE Rate*
n=1 Report line speed, DTE speed and Link protocol
n=2 "CONNECT" Reports Link speed
Xn - Result Code Set - ATXn selects which set of result
codes the modem may send.
n=0 Result codes 0 to 4
