MX9 Modular integrating access multiplexer

The compact, modular Kilomux time-division multiplexer transports data, voice, fax and LAN traffic over one or two main links, at rates of 9.6 kbps to 1536 kbps each.
Kilomux can be connected to various services including leased line, DDS, ISDN or Fractional E1/T1. Main link buffers and echo cancellation on voice channels ensure full operation over radio and satellite. Kilomux features both analog and digital voice interfaces for direct connection to PBX tie lines and extensions, ISDN PBX extension lines, telephone handsets and E1/T1 trunks.

The unit uses time-division multiplexing (TDM) techniques to ensure minimal delay and protocol transparency, so that applications such as SNA and voice are assured the bandwidth and short delay they require.

Kilomux traffic can be transported over IP or Ethernet-based networks, using its TDMoIP® main link module. The unit transmits high quality voice (either compressed or uncompressed). It employs two encoding methods: PCM (64 kbps) and ADPCM voice compression techniques for voice, fax and data transmission (32 kbps). The MPMLQ voice compression algorithm enables voice, fax, and data transmission at rates ranging from 16 kbps down to 4.8 kbps. Standard fax and data modem relay rates are between 14.4 kbps and 2.4 kbps. Kilomux can be used in point-to-point applications between two sites, or in "V"; or chain applications for multiple sites. The unit supports two independent configuration databases (day/night) and can switch between them in case of any network event. This feature enables alternate routing in case of failure. Various timing modes are available, enabling the system to use the received clock from a main link, a subchannel or an internal oscillator clock.

Management

Kilomux system operation and management, including configuration, diagnostics and monitoring local and remote units, can be performed via ASCII terminal, Telnet, or RADview. An ASCII terminal can be connected locally, through dial-up modem or via Telnet.
RADview, RAD’s Network Management System running over PC or UNIX (HP OpenView), monitors and controls multiple Kilomux-2100/2104 chassis from a central station via a user friendly GUI. The system provides direct online supervision, configuration, diagnostics and alarm reception. Storing all configuration information in non-volatile memory ensures data integrity in the event of power failure.

Kilomux chassis

The Kilomux product line features two chassis models for different network requirements. The modular Kilomux design enables upgrading and customizing the system by adding System and I/O modules.
Kilomux-2100 is a modular, 3U-high device that supports system modules, up to 12 I/O modules, and optional redundancy for main link and power supply. Kilomux-2104, with its compact size of only 1U, is designed for applications at smaller sites. It supports up to four I/O modules, and is limited to a single main link and a single power supply.

System modules

KCL.2, the Kilomux Common Logic control module monitors the system operation, sets configuration, and ensures communication with the management station. Common Logic modules can also be ordered separately for special purposes..

Main link modules

Several different types of Kilomux Main Link (KML) modules are available for compatibility with various digital data service interfaces and public services. Kilomux features a wide range of interfaces, such as: V.35, V.24/RS-232, X.21, G.703, Fractional E1/T1, ISDN Basic Access. The TDM over IP main link supports interfaces for 10/100BaseTx Ethernet networks.
Kilomux-2100 supports up to two main link modules. The second main link module can be used as a redundant link for backup, or as a load-sharing link to provide double capacity. KDI is a system module that provides drop-and-insert functionality between two Kilomux-2100 links, by bypassing any channel or combination of channels between link A and link B (see (see Figure 3). Refer to the separate KDI data sheet for more details..

I/O modules

Up to 12 I/O modules can be accommodated by the Kilomux-2100 chassis. Up to four modules can be accommodated by the smaller Kilomux-2104. The Kilomux high-speed sync KHS data modules operate at selectable data rates from 2.4 kbps to 614.4 kbps per channel. Interfaces supported include V.35, V.36/RS-449, X.21, RS-530, as well as BRI ISDN and G.703. The low-speed sync/async KLS modules operate at selectable data rates from 0.3 kbps to 64 kbps per channel.

The KVC voice and KVF voice/fax/ data modem modules support standard PCM and 32 kbps ADPCM voice, or high quality compressed voice. Advanced speech coding techniques include G.723.1 MPMLQ, which offers very high quality voice at bit rates as low as 6.4 kbps. Voice/fax/data modem modules feature automatic fax/data modem identification, which enables Group III fax and data modem transmission at rates of up to 14.4 kbps.

Both analog and digital voice interfaces provide connection to PBX tie lines, extensions or direct connection to telephones, as well as to E1/T1 trunks and ISDN PBXs. The Ethernet internetworking KMBE modules connect Kilomux to remote Ethernet LANs.

Diagnostics

Kilomux incorporates numerous test features for easy maintenance and fast fault detection. On power-up and during normal operation, automatic self-test and link-tests are performed. Any problems are reported to system management.
Local and remote loops can be performed for every main link and I/O channel via user commands. Additionally, a built-in BERT can test any I/O data channel.
