CANADIAN EQUIPMENT LIMITATIONS

Notice: The Canadian Industry and Science Canada label identifies
certified equipment. This certification means that the equi pment
meets certain telecommunications network protective, operational,
and safety requirements. The Department does not guarantee the
equipment will operate to the user’s satisfaction.

Before installing this equipment, ensure that it is permissible to be
connected to the facilities of the local telecommunications company.
The equipment must also be installed using an acceptable method of
connection. In some cases, the company’s inside wiring associated
with a single-line individual service may be extended by means of a
certified connector assembly (telephone extension cor d). Compliance
with the above conditions may not prevent degradation of service in
some situations.

Repairs to certified equipment should be made by an authorized Ca­nadian maintenance facility designated by the supplier. Any repairs
or alterations made by the user to this equipment, or equipment mal­functions, may give the telecommunications company cause to re­quest the user to disconnect the equipment.

Users should ensure for their own pr otection that the electrical ground
connections of the power utility , telephone lines, and internal metallic
water pipe system, if present, are connected together . This pr ecaution
may be particularly important in rural areas.

Users should not attempt to make such connections
themselves, but should contact the appropriate electric
inspection authority, or an electrician, as appropriate.

DIALING

Dialing from the Express is accomplished in the following ways:

• Using a VT 100 terminal connected to the rear panel EIA-232

port. (See

Express
Dialing

• Over the DTE interface using the AT command set. (See

Commands and S-Registers

• V.25 bis in-band (used in applications such as LAN/WAN

bridging). (See
on page 3-23.)

• When DTR is raised. Routers can be configured when band width

on their dedicated line is exceeded. In high-traffic times, this
allows the Express to dial out over the ISDN for an e xtra 128 kbps
of bandwidth-on-demand.

RECOMMENDED OPERATING PROTOCOLS

The Express supports a wide range of operating modes. Many combi­nations of circuit type, protocol, and data rate may be selected. The
combinations shown in Table 1-1 on page 1-5 are recommended.

Table 1-1 shows that a given data rate may be achieved by more than
one protocol/rate adaption selection. The table is organized so that
selections with the least transport delay are closer to the top of the ta­ble for any given circuit type. Therefore, choose a protocol and rate
closer to the top of the protocol rate list for a given circuit type.

Chapter 2. Installation

Verify Switch Settings

Dip switches 1 and 2 located on the rear panel of the Express 3010/
3110 allow you to physically configure certain settings. Figure 2-2
shows the location of the dip switches on the rear panel of the unit.

The factory default position for all switches is down (On) during ini­tial installation.

SW 1:

Off (Up) = 230.4 kbps

On (Down) = Autobaud (speeds up to 115.2 kbps)

If switch 1 is set to the Off position, the unit is set to operate at a DTE
rate of 230.4 kbps. A special COM port using a 16650 UART is re­quired while in this mode. If switch 1 is set to the On position, the unit
will automatically adapt to the DTE rate (up to 115.2 kbps).

SW 2:

Off (Up) = Factory Default

On (Down) = Normal (previous settings saved)

If switch 2 is set to the Off posit ion (up), the unit continue s to use the fac­tory default setti ngs until swi tch 2 is set to the On position (d own). Also,
area code, phone numbers, SPIDS, and stored numbers are cleared.

If both switches are up, the unit is offline in Command Mode.

Supplementary Voice Services

Supplementary services such as call forwarding, caller ID, call return,
call holding, three- or six-way conference calling, call transfer, call re­jection, and call waiting are fully supported by the Express 3010/3110
on a touch-tone telephone. These services are available only if includ­ed in the ISDN line configuration and are implemented using the stan­dard commands provided by the telephone company.

Call Waiting

Call Waiting permit s one voice c all to be placed o n hold while answerin g
another voice call. Use the flash-hook t o place the active call on hold and
answer an incoming call. Hanging up terminates both c alls. The call wai t­ing tone can be disabled and enabled on a per-call basis. To disable call

Phone Number Allocation

The Express allocates ISDN phone number 1 to POTS port 1. Connect
the primary telephone to POTS port 1 (see Figure 2-3).

21ISDN

Figure 2-3. Telephone Connection Port

ISDN phone number 2 is shared by the EIA-232 port and POTS port 2;
therefore only one port can be used at a time.

ISDN data calls and external modem applications must be placed to
ISDN phone number 2.

Auto-Detect SPIDs/Switch Type (Expert ISDN)
(Express 3010 Only)

Auto-detection of SPIDs and Switch Type greatly reduces the likeli­hood of time-consuming problems occurring during installation of
the Express. It evaluates common SPID formats based on the area
code and phone numbers and reports success after placing a test call.

The switch type and SPID numbers can be detected automatically
through the Express interface by using the following steps:

1. Type

2. Type

AT!V

Chapter 3

There are two methods for configuring the Express 3100: (1) by VT 100
terminal or (2) by AT commands. Before configuring the Express for
any application, the Express should be properly connected as de­scribed in the Chapter 2.

CONFIGURING THE EXPRESS

It is important to note that some features in the Express do not
immediately take effect upon selection. This prevents unintentional
reconfiguration of the Express during an active call. Items such as
Protocol and Call Type take effect only at the beginning of a new

Service Profile ID (SPID)

The SPID is a sequence of digits used to identify ISDN terminal equip­ment to the ISDN switch. The SPID is assigned by the local phone
company when the ISDN line is installed and it usually looks similar
to the phone number. Obtain SPIDs from your telephone administra­tor or local telephone representative.

The number of SPIDs required (0, 1, or 2) depends on how your ISDN
line is configured. For instance, a point-to-point line has no SPID.
Multipoint lines may have one or two SPIDs. The Express uses the
presence of SPID 1 to determine if the line is multipoint. If the line has
only one SPID, then it must be entered in SPID 1. Outside of North
America, the SPID format may not be used.

Example:

SPID 1 = 2 5 6
SPID 2 = 2 5 6 5 5 5 4 3 2 1 0 1 0 1

PREFIX SUFFIX

National ISDN-1 switches require the addition of a two-digit
terminal identifier (TID) at the end of the SPID.

SETTING PROTOCOL OPTIONS

The Express communicates with many different types of telecommu­nication equipment including other Express units, ISDN terminal
adapters, BONDING mode 1-compatible inverse multiplexers, and
PPP-compatible bridges/routers.

Communicating between such diverse types of equipment requires
the use of various rate adaptation protocols to support various bit
rates and DTE settings. The Express supports the following rate adap­tation protocols:

1. Clear Channel (no rate adaption protocol)

2. Point-to point protocol (PPP) asynchronous to synchronous con­version

3. BONDING mode 1 (Bandwidth on Demand Interoperability
Group)

4. CCITT V.120

5. CCITT V.110

6. FALLBACK

7. PPP async-sync

The desired protocol may be selected with AT commands at the DTE
port or from the Express built-in menu system. (With the built-in
menu system, view these protocol choices by press the number corre­sponding to
follows.

Point-to-Point Protocol (PPP) Async-to-Sync

PPP provides a standard method for transporting multi-protocol dat­agrams over point-to-point links. The ADTRAN PPP async-sync pro­tocol allows the Express and a PC or Macintosh
software, to communicate with a PPP-compatible bridge or router.
The PPP async-sync protocol complies with Internet Engineering Task
Force (IETF) RFC 1662.

The asynchronous control character map (ACCM) option is scanned
during the negotiation. When the ACCM option is seen in a configure
ACK link control packet, it is adopted by the Express. In addition,
when the ACCM option is not seen in the configure-request packet
from the network, the Express will spoof or add it to the packet.

Multilink Point-to-Point Protocol

This protocol allows the Express to dial a second number, establishing
a second point-to-point link. Once the second PPP is established, mul­tilink PPP is performed over both B-channels. The phone number for
the second call should be placed in stored number 1 (SN1). If no num­ber is stored in SN1, the same phone number dialed to establish the
first link is used for the second link.

PPP and STAC Compression

When set up to do compression, the Express will negotiate the com­pression control protocol (CCP) with the network PPP peer. If STAC
compression is successfully negotiated with the peer, data packets
from the DTE are compressed before being sent out the network. Like­wise, compressed packets from the network ar e decompressed before
being transmitted out the DTE.

Chapter 3. Application Configuration

CONFIGURING THE EXPRESS FOR V.25 BIS
IN-BAND DIALING

V.25 bis dialing is used primarily by DTE with synchronous interfaces.
The Express supports the following V.25 bis commands to control au­tomatic calling and answering:

CRN Call request (number in command)
CRS Call request (using stored number)
PRN Program stored number
RLN List stored number
CIC Connect incoming call
DIC Disconnect incoming call

When using stored numbers V.25 bis accesses stored numbers 1
through 9. See the section VT 100 Terminal Dialing Options on
page 3-6.

SYNC V.25 Dialing

V.25 bis specifies that the characters should be ASCII, 7 bits, with even
parity, and one stop bit. However, for versatility the Express allows
the data bits, parity, and stop bits to be changed as defined under
format.

Data

This setting allows for V.25 bis messages in asynchronous (start/stop)
data format.

In synchronous mode, the Exp ress is an IS DN ve r si on of a syn c hronous
modem. For configu rat ion o r troubleshooting, t he un it requires
connection to an async VT 100 terminal and the dial option must be set
to AT Commands. After the unit i s completely configu r ed, set the dial
option to V.25 bis and exit the VT 100 terminal interface. The unit is
now ready to respond to V.25 bis dialing commands. If it is necessary to
reenter the VT 100 interface for re -configuration, tr ouble shooting or to
view the status buffer , perform the foll owing steps: (1) power the unit off,
(2) set dip switch 2 to off (up) for factory default AT commands, (3)
powe r t h e u nit back on, (4 ) set d i p s w i tch 2 t o o n ( d own), a n d (5) type

to activate the terminal interface.

Chapter 3. Application Configuration

SYNC V.25 HDLC Dialing

Although V.25 bis allows asynchronous data format, asynchronous
DTE is more likely to support the AT command set than V.25 bis.

This sett ing provi des V.25 bi s messages in bit-sy nchronous format (fo r
example, HDLC, SDLC, X.25). The bit-synchronous format is the most
commonly used by V.25 bis.

This option specifies that the characters should be 7-bit ASCII, with
the 8th bit ignored (it may be either 0 or 1).

The first byte of each packet contains all one bits (A = FF HEX), and
the second byte of each packet (the C byte) is either 13 HEX or 03 HEX
if not the final packet.

Select V.25 HDLC flags if your terminal equipment requires idle
state flags.

SYNC V.25 BISYNC Dialing

This setting allows for V.25 bis messages in byte-synchronous format
(BISYNC). V.25 bis specifies that the characters should be ASCII, 7
bits, and odd parity. This setting allows synchronous DTE which does
not use HDLC to support serial in-band dialing.

Auto-detect Switch/SPIDs Remains at Link
Down

The Link Down condition persisti ng for longer than fiv e minu tes indi­cates a problem with the ISDN line provided from the telephone compa­ny. The ISDN physical layer device has not been able to sync hronize to
the network. Ensure that the RJ-45 to RJ-11 telephone cable is correctly in­stalled between the Express and the ISDN wall jack and that the Express
is powered on. If the wall jack does not have ISDN installed on the two
middle pins (tip, ring), the Express will never synchronize t o the tele­phone switching equipment. Call the local telephone company and hav e
them check the ISDN line for correct operation.

Express Not Detected

If the Express Configuration program cannot detect the Express, veri­fy the following:

1. The Express is powered on.

2. No other applications are running that could be using the COM

port to which the Express is attached. A Windows application
does not have to be active to tie up a COM port. Be sure to check
the Windows 95/98 Taskbar for any suspended applications
(such as HyperTerminal) that may be using the COM port. If any
are minimized, these must be closed before starting the Express
Configuration program.

3. If you are operating at 230.4 kbps, Switch 1 to Off (up). Also, con-

firm that the computer has a 16650 UAR T.

Chapter 6. Troubleshooting

Difficulty with 230.4 kbps Operation

If the Express does not work when the DTE rate is set to 230.4 kbps in­side Windows, verify the following:

1. Verify that switch 1 on the back of the Express is set to Off (up).

2. Verify that a high speed serial card with a 16650 UART is being
used and the software drivers to support the extended baud rate
tables are installed.

Dial-Up Networking Difficulty

If Windows 95/98 Dial-Up Networking cannot talk to the Express,
check the modem configuration for the Express. Ensure the bit rate for
the DTE is set correctly. If the PC is not equipped with a 16650 UART,
then the fastest DTE operation speed is 115.2 kbps. Ensure the speed
is not higher than the PC and modem can support.

Appendix A

While a call is not established, the DTE port accepts AT co mmands.
During this time, the CD signal is inactive. When a call is established,
the port is used for data. This data mode is indicated by the CD signal
active. The Express can be configured and controlled with AT com­mands from a serial port similarly to analog modems.

To exit data mode and enter command mode, the serial port must
transmit a proper escape sequence to the Express. A specified time de­lay must occur between the last data character and the first escape se­quence character. This is the guard time delay, and it can be changed
by writing a value to the S12 register. The default value for the guard
time is one second. For a valid escape sequence to occur, the DTE
must transmit the escape code character three times in succession with
delay between each character being less than the guard time. The de­fault escape sequence is

Once command mode is entered, AT commands can be transmitted to
the Express to configure most of the options, dial remote Expresss, or
initiate tests to check the Express and the network connections. All
command lines must begin with the AT character set in either capital
or lower case letters. To return an active call to the on-line state type

AT Commands and S-Registers

Commands may be separated with spaces for readability. The maxi­mum length for a command lin e is 40 characters. Each comm and line
is executed by the Express upon receipt of a terminating character.
The default terminating character is a carriage return (ASCII 013), but
it can be changed by writing a different value to r egister S3. Before the
terminating character is transmitted, the command line can be edited
by using the backspace character (ASCII 008) to erase errors so the
proper commands can be entered.
