MultiVOIP User Guide Technical Configuration (Digital) 121 E1 Parameter Definitions Field Name Values Description T1/E1/ISDN E1 European standard. Long-Haul ModeY/N In Long-Haul Mode, the MultiVOIP auto-matically recovers received signals as low as –36 dB. The maximum reachable length with 22 AWG cable is 2000 meters. When Long-Haul Mode is disabled, signals as low as –10 dB can be received. Default: disabled. CRC Check (Cyclic Redundancy Check)-- Not applicable to E1. Frame Format Double Frame; MultiFrame (with CRC4); MultiFrame (w/CRC4, modified)Frame Format of MultiVOIP should match that used by PBX or telco.
MultiVOIP User Guide Technical Configuration (Digital Voips) 122 E1 Parameter Definitions (cont’d) Field Name Values Description CAS Protocol E&M Immed Strt E&M Wink Start E&M Wink with dial tone FXO Ground Strt FXO Loop Start FXS Ground Strt FXS Loop Start MFR2ITU MFR2 China MFR2 ANIChannel Associated Signaling (CAS) is a method of incorporating telephony signaling info into an E1 voice/data stream. In CAS, the signaling bits (the A, B, C, and D bits) are multiplexed into the signal stream of each E1 channel. (By contrast, in Common Channel Signaling (CCS), one channel handles signaling for all other channels.) Each CAS protocol defines the states of the signaling bits during the various stages of a call (IDLE, SEIZED, ANSWER, RING-ON, RING-OFF). The CAS protocol code allows the VOIP to interact properly with the PBX or central-office switch that it serves. The need to download CAS protocols arises for only a small minority of VOIP users, and only when PBX/switch is found to be incompatible with standard protocols. Match this parameter to the setting of PBX or central-office switch.
MultiVOIP User Guide Technical Configuration (Digital) 123 E1 Parameter Definitions (cont’d) ISDN Parameters Field Name Values Description Enable ISDN-PRIY/N If digital connection is ISDN- PRI type, this box should be checked. When ISDN is enabled, the “CAS Protocols” field is grayed out (ISDN has its own signaling method). Terminal/ Networkeither “Terminal” or “Network”When “Terminal” is selected, it indicates that the MultiVOIP should emulate the subscriber (terminal) side of the digital connection. When “Network” is selected, it indicates that the MultiVOIP should emulate the central office (network) side of the digital connection. Setting used for MultiVOIP must be opposite to the setting used in the PBX. For example, if the PBX is set to “Terminal,” then the MultiVOIP must be set to “Network.” Country see table, later this chapterCountry in which MultiVOIP is operating with ISDN. Operator see table, later this chapterIndicates phone switch manufacturer/model or refers to telco so as to specify the switching system in question. ISDN is implemented somewhat differently in different switches. Note on Country & Operator options.__ [ISDN implementation options are shown, arranged by country, in a table below – soon after E1 Parameter Definitions.]
MultiVOIP User Guide Technical Configuration (Digital Voips) 124 E1 Parameter Definitions (cont’d) Field Name Values Description Line Build Out 0 dB, -7.5 dB, -15 dB, -22.5 dBTo reduce the crosstalk on received signals, a transmit attenuator can be placed in the data path. Transmit attenuation is selectable. Default: O dB Pulse Shape Level0 to 40 Meters 40 to 81 m 81 to 122 m 122 to 162 m 162 to 200 mRefers to length of cable between MultiVOIP and PBX/telco in meters. Most common will be 0 to 40m. Clocking External/Internal Set opposite to telco/PBX setting. Example: if telco clocking internal, set VOIP clocking as external. Line Coding AMI / HDB3 Match to PBX or telco. PCM Law A-Law/Mu-Law Match to PBX or telco. “A-law” is analog-to-digital compression/expansion standard used in Europe. “Mu-law” is North American standard.
MultiVOIP User Guide Technical Configuration (Digital) 125 10. Set ISDN Parameters (if applicable). These parameters are acces- sible in the T1/E1/ISDN Parameters screen. If your T1 or E1 phone line is a Primary Rate Interface ISDN line, enable ISDN-PRI and set it for the particular implementation of ISDN that your telco uses. The ISDN types supported by the digital MultiVOIP units (at press time) are listed below, organized by country.

To make the MultiVOIP controllable by a remote PC running the MultiVoipManager software, check the “Enable SNMP Agent” box on the SNMP Parameters screen. Accessing “SNMP Parameters” Pulldown Icon Shortcut Sidebar Ctrl + M
MultiVOIP User Guide Technical Configuration (Digital) 127 In each field, enter the values that fit your particular system.
MultiVOIP User Guide Technical Configuration (Digital Voips) 128 The SNMP Parameter fields are described in the table below. SNMP Parameter Definitions Field Name Values Description Enable SNMP AgentY/N Enables the SNMP code in the firmware of the MultiVOIP. This must be enabled for the MultiVOIP to communicate with and be controllable by the MultiVoipManager software. Default: disabled Trap Manager Parameters Address 4 places; n.n.n.n n = 0-255IP address of MultiVoipManager PC. Community Name-- A “community” is a group of VOIP endpoints that can communicate with each other. Often “public” is used to designate a grouping where all end users have access to entire VOIP network. However, calling permissions can be configured to restrict access as needed. Port Number 162The default port number of the SNMP manager receiving the traps is the standard port 162. Community Name 1Length = 19 characters (max.) Case sensitive.First community grouping. Permissions Read-Only, Read/WriteIf this community needs to change MultiVOIP settings, select Read/Write. Otherwise, select Read-Only to view settings. Community Name 2Length = 19 characters (max.) Case sensitive.Second community grouping Permissions Read-Only, Read/WriteIf this community needs to change MultiVOIP settings, select Read/Write. Otherwise, select Read-Only to view settings.

MultiVOIP User Guide Technical Configuration (Digital Voips) 130 The Regional Parameters screen will appear. For the country selected, the standard set of frequency pairs will be listed for dial tone, busy tone, ‘unobtainable’ tone (fast busy or trunk busy), and ring tone. In each field, enter the values that fit your particular system.
