NECA 340-414-300 Revision 2.0 Page 5 of 6 MCU 5000A Multipoint Control Unit INT-001 4: TRANSMIT FORMAT4.01 There are three types of data transmit formats which are issued from the MCU console and MCU 5000A or vice versa: (1) Command Transmit Format, (2) Response Transmit Format, and (3) Global Indication Transmit Format. A. Command Transmit Format 4.02 A command is sent from the MCU console to the MCU 5000A in the following format: COMMAND field : Contains an input command (4 letters). SPACE field : A command and parameter(s) should be separated with a space. PARAMETER field : Contains input parameter(s). Multiple parameters should be separated with a space . CR+LF field : Contains the signal which is generated when the RETURN key on the keyboard is depressed. B. Response Transmit Format 4.03 The MCU 5000A returns a response to an input command from the MCU console. There are two types of responses: a normal response and an error response. Normal Response A normal response format is as follows: RESPONSE : Contains a response message (parameter(s) and CR+LF (PARAMETER signal). CR+LF) field Note: The parameter(s) and CR+LF signal contained depend upon the input command. OK field : Contains OK which indicates the successful completion of an input command. COMMAND SPACE PARAMETER (PARAMETER …) CR+LF PARAMETER (PARAMETER CR + LF)CR+LFOK

C. Global Response Indication Transmit Format 4.04 When any event occurs or the status changes in a system, the MCU 5000A sends global indication to all MCU consoles and terminals in the following format: INDICATION : Contains an indication name (4 letters). NAME field SPACE field : An indication name and a parameter field are separated with a space. PARAMETER field : Contains parameter(s). ERROR CODE CR+LF INDICATION NAME SPACE PARAMETER (PARAMETER …) CR+LF
NECA 340-414-300 Revision 2.0 Page 1 of 2 MCU 5000A Multipoint Control Unit COP-110 CGPR System Setting COMMAND NAME auto start Command Generator PRogram PURPOSE This command is used to create the auto start command generator program, which is stored in the memory card as the command generator file. When the MCU 5000A is powered, the command(s) registered in this file is automatically executed (the command generator file is similar to the MS-DOS batch file). Note 1: The write protect switch located on the memory card should be set to “OFF” position before entering this command. Note 2: If the incorrect command is registered by this CGPR command, the MCU 5000A cannot possibly start up. Note 3: The command generator file is stored only on the memory card. INPUT FORMAT CGPR__vv.vv ¿ (OK) (See Note (1)) A 1 A2 . . . A i CGPE ¿ (OK) (See Note (1)) EXPLANATION OF INPUT PARAMETERSvv.vv= (0-9) (0-9).(0-9) (0-9) Specifies the version number for which the Auto Start generator program will be identified. Valid values for v are: 0 through 9 A 1-Ai: Specifies the command registered in the command generator file. Note 1: OK within parentheses is not entered, but indicated. Note 2: CGPE command must be entered at end of command input string. Note 3: The input data must be less than 4 k-byte. If input data exceeds 4k- byte, overflow occurs.

The status are indicated as follows: (1) 1.5M-LIF (CH1 to CH4:) Line Status 0: LIF card is not mounted. 1: Normal 2: RAI signal is received. 3: Data clock is out-of -synchronization. 4: AIS signal is received. (2) RS-422 (CH1 to CH4) Line Status 0: LIF card is not mounted. 1: Normal 2: I signal is not received. 3: Data clock is out-of-synchronization. (3) H0-LIF (CH1 to CH2) Line Status 0: PKG unmount 1: Normal 2: Receive RAI 3: Synchronous failure 4: Receive AIS D: Disconnect L: Establish INPUT FORMAT LSTQ ¿
