Introduction Introduction About the document The Meridian Communications Adapter (MCA) is an interface that supports many desktop applications. This User Guide describes how to use the MCA to interface with these desktop applications and the Meridian 1. This guide displays information pertaining to synchronous operation in italic type. The Meridian Communications Adapter (MCA) passes synchronous and asynchronous data through Nortel Networks systems by using the M3900 Series Meridian Digital Telephone.
Introduction M3900 series telephone.Once the ACM is installed, the MCA cartridge accessory is inserted into the ACM to provide an interface to data functions. To install the ACM refer to the Accessory Connection Module Installation Guide packaged with the ACM. Use the following procedures to install the MCA to the telephone: • Plug the MCA Accessory Cartridge into the ACM opening in the back of the telephone footstand.
Dialing methods Dialing methods The MCA provides three methods for making data calls through the Nortel Networks PBX: keyboard dialing, AT dialing, and keypad dialing. You use Keyboard and AT dialing by entering commands at a terminal or on a PC running software to make it emulate a terminal. Keypad dialing is done through the telephone keypad. Keyboard dialing is menu driven. Data calls are made by pressing the < CR > to get the Main menu.
Make a data call Make a data call The procedures in this section describes how to make basic data calls. There are three methods used to make a data call; keyboard dialing, AT dialing and keypad dialing. Note: Throughout this guide, refers to a Carriage Return. Keyboard dialing 1. Press the Carriage Return. ENTER NUMBER OR H (FOR HELP) £ and 2. Enter the number of the far end data device and Press the Carriage Return . CALL CONNECTED SESSION STARTS 3.
Make a data call Keypad dialing Keypad dialing is accessed through the Options. Press the Options Key and use the Navigation Keys to scroll to MCA data parameters. Once you are familiar with your MCA option number, you can press the Options key and dial the MCA data parameters option number, followed by the parameter number. • The Options Key on the M3902 is on the right side of the telephone. • The Options Key on the M3903 and M3904 is on the front edge of the telephone.
Make a data call Release a data call To release a call while in asynchronous mode, use any of the following methods: Break Break Break or Options / + • or Press the Break Key(s) on your PC keyboard for 1.6 seconds or longer. Note: This method is not supported on terminals with non-overlapping timed break. Press the Break Key(s) on the PC Keyboard three times in quick succession. The break must be at least 100 milliseconds and all three breaks must be within one second.
Make a data call Default parameters for Asynchronous and Synchronous The MCA is configured in asynchronous mode when it is shipped from the factory. The MCA defaults to synchronous or asynchronous mode from the telephone. The mode is determined prior to resetting the parameters. Listed here are the default parameters. The mode is determined prior to resetting the parameters. Refer to the “Reset data parameters” section in this guide for more information.

Ring Again is activated and notifies you when the far end is free.
Keyboard dialing Display parameters (asynchronous) To list information about MCA configuration from the terminal: P Select P (display parameters) and press the Carriage Return. The following example shows the items listed with possible values for each. The first three parameters give information on the current version MCA you have (they do not change). For more detailed descriptions of these parameters, see Keypad dialing. Engineering code = NT2K0047 Release = 01 Firmware = 3.
AT dialing AT dialing AT dialing is similar to the methods used to make data calls with a Hayes Smartmodem. Some AT commands do not apply to the MCA, and are not supported. Most AT commands begin with the letters AT (not case sensitive). These two letters are followed by a one- or two-character command (sometimes followed by additional parameters) and a carriage return. Each command line is limited to a maximum of 40 characters (not including the AT and spaces).
AT dialing ATOn (on-line, where n = 0, 1) This will put you on-line if you had previously used the escape code (three escape characters) to go off-line. The same result applies to both case n = 0 and n = 1. ATQn (result code, wheren=0,1) Result codes (call progress prompts) are not sent to your terminal when n = 1. That is, you will not see call progress prompts. When n = 0 result codes are sent to your terminal. ATV n (verbal result, where n = 0, 1) Verbal prompts are sent to your terminal when n = 1.
AT dialing ATZn (soft reset, where n = 0, 1) This returns S0 through S49 registers and AT configurations to their default settings. The same result applies to both case n = 0 and n = 1. Registers S50 through S69 will be reset to their default values only upon power-up. The following commands are extensions to AT dialing used to support the MCA. ATDPxxxx (voice call, where x = 0–9) This allows you to make a voice call from your terminal. The digits, xxxx, represent the number of the person you wish to call.
AT dialing ATIn (product identification code, where n = 0, 1, 4) When n = 0, the MCA displays the contents of S-registers S52–S54. The default is “960” (Smartmodem V-series 9600 modem). Other possible values are: “122” (Smartmodem 1200) and “240” (Smartmodem 2400). When n = 1, the result is “206.” When n = 4, the result is “a037800c004420” and then “b100000000” (these are the same values that Smartmodem V-series 9600 returns).
S-registers AT&Yn (recall user profile on power-up, where n = 0, 1) This returns S0 through S49 registers and AT configurations to their default settings. The same result applies to both case n = 0 and n = 1. To enter the AT command state from the on-line data transfer state: Off-line mode Esc Esc Esc 1. Press the escape character three times in quick succession. ATH0 2. To return to a command mode (AT or keyboard dialing) while also dropping the call, use the break key(s). Enter ATH0.
S-registers S1 (ring count; read only) This returns the current number of rings for an incoming data call when read. S2 (escape character; range = 0–255) This holds the ASCII value of the escape character. If the S2 register is set to a value of 128 or greater, then escape character action is disabled. S3 (carriage return character; range = 0–127) This holds the ASCII value of the carriage return (used for command line termination and prompt termination). The default is 13.
S-registers S8 (pause time for comma; range = 0–255) A comma included in the dialing sequence is interpreted as a delay. The default delay time is two seconds. S12 (escape code guard time; range = 0–255) The guard time aids in recognition of the escape sequence, useful since different numbers of escape characters mean different things.
S-registers Dial modifier Dial modifiers are special parameters used to tell the MCA how to dial the data number. Description Modifier Digit for dialing 0–9 Characters for dialing ABCD While dialing, instructs PBX to begin dialing the digits entered to this point. After dialing, this character is outpulsed as tone. # After dialing, this character is outpulsed as a tone. * Delay processing for a period of time, set by S8 register. Default is two seconds.
Introduction to Keypad dialing Introduction to Keypad dialing Keypad dialing can be used in both synchronous and asynchronous mode. The MCA data parameter commands accessed through the Options Key, require a Display on the telephone. Keypad dialing commands are most useful for making simple data calls or for modifying the MCA configuration. The M3902, M3903, M3904, and M3905 access the MCA data parameters through the Option Key. • M3902 Option Key - one of the fixed key on the right side edge of telephone.
Introduction to Keypad dialing Note 1: When you have given a Keypad command to the MCA, it remains in that mode until you press the Options Key or Quit Key. Note 2: You cannot make an outgoing call while in an active MCA command. Note 3: You can receive calls while the MCA is performing an active command. Options / or Quit Example: MCA data parameter Keypad dialing command for Ring Again: Options / 6. Press the Options Key or Press the Quit Key to end session.

Additional asynchronous features CALL CONNECTED.SESSION STARTS Additional synchronous information Use fifi and fi‡ (HDLC On) for Group IV FAX. Use fifi and fifl (Bisync On) for video. When V.25 fifi) is turned on, the MCA automatically switches to synchronous mode. When in the V.25 mode, auto answer is not available. If an MCA in synchronous mode calls another data module in asynchronous mode, the call is connected. You must drop the call.
Additional asynchronous features Voice call origination By using a special cable, the MCA can communicate with two DTEs at the same time. The primary channel is the main communication channel offering MCA features. The second channel can respond to Voice Call Origination commands (VCO) only. This provides the ability to make a voice call across the second channel while simultaneously using the primary channel to transmit or receive high speed data. Below is the pinout list to connect the second channel.
Asynchronous troubleshooting Asynchronous troubleshooting If data is sent in idle mode (when there is no active call), you can not use keypad dialing. You must stop sending the data from the DTE. You must disconnect pin 22, if you are using an RS-232 cable to connect the MCA to an ADM3/5 terminal. If you are changing the MCA from Synchronous to asynchronous, change the baud rate before you change the mode from synchronous to asynchronous. Some terminals drop DTR with this mode change.
Asynchronous troubleshooting Symptom The prompt: CALL CONNECTED.SESSION STARTS Solution 5. If you have a Display on your telephone, dial fl‹get into EIA Monitor mode. Check to see that the MCA is receiving signals from your terminal by watching the RXD indicator on the Display while entering carriage returns on the keyboard. If the indicator flashes, the connection is correct. If not, make sure the cable connection is secure and the cable is a standard RS-232. 6.
Asynchronous troubleshooting Symptom Solution MCA does not operate at all. 1. Check the LED in the back of the telephone to see if it is flashing. If the LED is steadily lit, the MCA needs to be configured in your system, or the MCA is not functioning correctly. If the LED is not lit, the MCA requires external power. 2. Make sure the cable from your terminal or PC is connected to the MCA. - Check the data parameters for your display.
Synchronous troubleshooting Synchronous troubleshooting After the call is connected send the data using bit error rate testers (BERT). If there is no transmission, or if there are excessive errors, the MCA is probably defective. Return it for repair.
