For voice traffic, it supports the following interfaces:

• FXO
• FXS
• E&M (2Wire / 4Wire)
• Hot-Line (Ring-Down)
• Ring Generator (75V RMS)

For data traffic, it supports the following interfaces:

• Channelized E1 / Fractional E1 data with full cross-connect capability at 64Kbps, DS-0 level.
• RS-232 asynchronous data.
• Sub-rate multiplexing to provide 4 asynchronous data channels in a single 64Kbps time-slot.
• V.24 synchronous / asynchronous data.
• G.703, @ 64 Kbps, co-directional data.
• V.35, V.36, X.21, V.11, RS530, RS449 synchronous, "n"x64Kbps data.
• Relay I/O Card (Dry Contact).
• IEEE C37.94 Teleprotection Interface.
• Universal DCE/DTE synchronous "n"x64Kbps data.
• 8E1 plus 100Mbps Ethernet fiber optical transport interface along with the following:
• EOW (Engineering Order Wire) channel for end to end installation and maintenance.
• Local and remote loop back for diagnostics.
• 1+1 Fiber Path protection.
• ALS (Auto Laser Shutdown) facility for eye safety.
• 10/100M Ethernet Port - 100 Mbps Ethernet data transmission rate complies with IEEE 802.3.

Highlights

• Field upgradable to provide voice, data or both services.
• Flexibility on use of transmission medium-copper, fiber or wireless.
• Choice of Interfaces for Voice and Data Applications.
• USB and RS232, Interface for local connection through the serial interface to the "Network Control and Management Software".
• Channel assignment independent of slot position in the sub-rack.
• Extensive set of alarms.
• User Selectable Internal, External and Loop-timed clock synchronization priority options.
• Universal slots - any interface card can plug in at any interface slot.
• OAM Card.

System Access, Control and Management Options:

• Telnet
• SSH
• CLI Control Interface (HyperTerminal or VT100)
• SNMP V2 Traps (MIB File provided).

OAM: Operation and Management Ports

• RS232 Serial Port
• USB COM Port
• 10/100BaseT Ethernet for remote access.

Security and Protection

• Secured Access via SSH V2.
• Password Protection: Password Protection in compliance with the mandatory clauses of the GR-815-CORE-2 specifications for secured access control.
• Logging: Maintains a log of all successful and un-successful attempts. Logged information includes the ID and the IP address of the accessing entities. Alerts the administrator if the un-successful logging attempts exceed 3.
• Security Audit: All access logs for up to 30 days are maintained for security audit purposes.
• Security log entry of any request or activity including that user-ID (including IP address, if applicable), to establish user accountability.
• Report Generation / Audit Trail.
• Security Administration.

Transmission Mediums

The VCL-MX offers an excellent flexibility on the choice of transmission medium over which it may be deployed. The transmission medium can be either of the following:

• Copper
• Optical Fiber
• Wireless.

Configuration and Flexibility

VCL-MX Version 6 - E1 160Mbps Multiplexer can be configured as an Add-Drop Multiplexer (ADM) and Terminal Multiplexer (TMUX). It can support diverse topologies like point-to-point, ring, star and tree. It can be configured in various topologies supporting both electrical and optical interfaces. It can take modular cards, which would enable the customers to start small and grow as traffic demands scale.

Synchronization

System Management

VCL-MX Version # 6 - Voice and Data Drop-Insert Multiplexer offer a variety of management options, The VCL-MX E1 multiplexer management software can be configured using CLI (English text) commands and GUI (Graphical User Interface). The management and configuration commands may be executed from a VT100 terminal, Windows HyperTerminal, any DOS based system, Linux or UNIX based system, or Telnet (remote management).

The equipment provides a wide choice of access ports for connecting to and executing management and configuration commands through its OAM Card.

The OAM card provides:

• COM Port (RS232 Serial Port)
• USB Port
• 10/100BaseT Ethernet Port (each multiplexer may be assigned an IP address and connected to a LAN / IP network for remote access and management through the 10/100BaseT Ethernet Port for out-of-band configuration, management and access)
• Telnet
• SSH
• SNMP V2
• Additionally, a Windows based GUI (Graphical User Interface) for easy configuration, management and access.
• The VCL-MX has an effective, CLI (text) and GUI based "Network Management Interface", which may be used for configuring and monitoring multiple systems from a single central location.
