The Kilomux-2100 sub-rate multiservice multiplexer provides an efficient and cost-effective solution for integrating data, voice, fax, and LAN traffic over digital data services, leased lines, IP, ISDN, and other services. Access to the various services is provided over a variety of standard interfaces at data rates ranging from 9.6 kbps to 1,536 kbps.
The low overhead, minimal end-to-end delay and allocated bandwidth of the Kilomux – together with voice compression – ensures quality of service (QoS) while maximizing utilization of the available bandwidth.
Many interfaces are available on the aggregate links for compatibility with digital data services worldwide. These include V.35, V.36/V.11, RS-530, V.24/RS-232, X.21, and G.703 co-directional. Built-in CSU/DSU, fractional E1/T1, fiber optic, ISDN terminal adapters, and TDMoIP are also available. Soft-selectable timing options from either the link or any channel are standard for all interfaces, as is support for control signals.
Standard 8-bit buffers on both the transmit and receive lines, as well as an optional onboard 256-bit satellite buffer, enable the use of any type of access media. These include leased lines, fiber, radio, microwave, and satellite links.
The Kilomux-2100 sub-rate multiservice multiplexer supports a secondary link, which can be configured in several ways:
-
As a backup link, which can be connected to a dial-up modem, switched digital service or ISDN basic rate line.
-
As an active, secondary link with load-sharing option providing double capacity. This mode supports "priority bumping," which allows the most important channels to continue functioning in the event of a failure on either link.
-
As an additional, active link, thus enabling communication with two independent Kilomux-2100 units at different sites. In this configuration, the KDI module can provide drop-and-insert and bypass capabilities between the two links.
Main link modules include:
KML.1/N for V.35 interface
KML.2/N for V.24/RS-232 interface
KML.3/N for V.36/RS-422/RS-530 interface

Drop-and-insert and bypass module. The KDI can be used in situations where the Kilomux at the central site is communicating with two remote sites and voice/data communication is required between the remote sites. In addition, it can provide support for ring topologies and a single multidrop channel.
KM-Ringer provides DC feed and ringer voltage for voice modules with FXS interface
Alarm indication module for rear panel viewing of most front panel indicators.
Various timing options for both the link and the I/O channels assure integrity of data transfer in any application. DTE, DCE and external DCE clocking are supported by the main link (not applicable on G.703 or CSU/DSU).
I/O modules are available for many types of traffic. Low and high bit rate data (sync and async) channels can be combined with voice and fax circuits for maximum bandwidth utilization. Advanced technology in voice compression allows a choice between toll quality ADPCM, PCM or high-quality, low bit rate compressed voice, at rates as low as 4.8 kbps. In addition, internetworking modules provide LAN (Ethernet) connectivity.
Any combination of up to 12 I/O modules can be configured in the Kilomux-2100 chassis.
Low-speed module supports two sync or async RS-232/V.24 data channels. Selectable data rates from 300 bps to 64 kbps.
Statistical multiplexing data module supports four async RS-232/V.24 channels. Selectable data rates from 300 bps to 19.2 kbps.
High-speed module supports two sync data channels with V.35, RS-449/RS-422 or X.21 interface. Supported data rates are 32, 48, 56, 64, 128, 192, 256 and 384 kbps.
High-speed module supports two sync data channels with V.35/RS-530, V.36/RS-530 or V.24/RS-232 interface. Supported data rates:
-
n x 2.4 kbps for link rates up to 192 kbps
-
n x 4.8 kbps for link rates of 256 kbps and 384 kbps
-
n x 9.6 kbps for link rates of 512 kbps and higher
High-speed module with one data channel, supports ISDN basic rate services even over non-ISDN facilities such as dedicated leased lines. The KHS.U operates either as NT (Network Termination) or LT (Line Termination).
High-speed module supports two 64 kbps G.703 co-directional channels.
Voice module supports two analog voice channels with ADPCM encoding at 16, 24 or 32 kbps. Also supports PCM encoding at 64 kbps (A-law). Modular analog interfaces are 2/4-wire E&M, 2-wire FXS, FXO and FXSP. Additionally, it offers pulse metering at 16 or 12 kHz and polarity reversal, as well as optional echo cancellation.
Voice/fax low bit rate module uses the ITU G.723.1 voice digitizing technique to provide toll quality voice at 6.4 kbps for two analog channels or an ISDN S interface channel (including D-channel compression). The card can digitize voice at rates from 4.8 kbps to 12.8 kbps and offers pulse metering at 16 or 12 kHz and polarity reversal as well as integral echo canceller. Analog interfaces supported are E&M, FXO, FXS, FXSP, and FXSW.
Voice/fax low bit rate module uses the ITU G.723.1 voice compression algorithm to provide toll-quality voice at 6.4 kbps for a full E1 or T1 trunk. The card can digitize voice at rates from 4.8 kbps to 16 kbps and supp orts inband transparent fax transmission at rates of up to 14.4 kbps. The dual-slot module supports both CAS (DTMF,R2) and CCS (SS7,PRI) signaling methods.
Voice/fax low bit rate module uses the G.723.1 digitizing technique to provide toll-quality at 6.4 kbps for eight analog channels. The card can digitize voice at rate s from 4.8 kbps to 16 kbps and supports inband transparent fax transmission rates of up to 14.4 kbps. The card offers pulse metering at 16 or 12 kHz and polarity reversal as well an integral echo canceller.
All KVF modules support inband fax for transparent fax transmission as well as V.22 and V.22bis modem data transmission. KVF.6 and KVF.8 also support V.32bis modem data transmission.
Ethernet IP/IPX router/bridge module supports the connection of up to 256 remote workstations to main Ethernet LAN in bridge mode, and to an unlimited number of workstations in router mode. Bandwidth from 9.6 kbps to 1,280 kbps is supported on the link. Interface can be AUI, thin coax or UTP (10BaseT). The module includes all the features of the WEB RANger-II such as Single IP, Solid Firewall and RADview SNMP management.
The Kilomux offers three management options:
1) ASCII terminal – An ASCII terminal can be connected locally or remotely, using a dial-up modem.
2) Telnet: a Telnet client can be used to control the Kilomux via its Ethernet management port or via an inband management channel.
3) RADview management station – enables complete monitoring and control from a central management station. RADview provides direct on-line supervision, configuration and diagnostics.
The Kilomux devices include an SNMP agent and can be managed using RADview-PC or RADview-HPOV (on a UNIX platform) graphical user interface.
This provides terminal access to remote devices from any management station on the network for configuration and troubleshooting.
Audio and visual indicators provide the status of alarms and tests at the network, multiplexer, card and port levels and include all links connected to the Kilomux. Alarms are automatically logged and presented upon request unless otherwise masked.
Configurations are automatically checked for validity before being downloaded or upon user request. This check can be performed at three different levels: the whole network, one single rack or per module or channel.
Network-level operations enable easy activation of drop-and-insert applications. An existing configuration can be copied to a desired destination within the same Kilomux or to any other Kilomux. This operation can be performed at the Kilomux, card or channel level.
All configuration parameters are stored in non- volatile memory to ensure data integrity in the event of a power failure. A secondary database may also be programmed for time-of-day bandwidth allocation or switched backup operation. Alarm information is collected and stored in memory for easy reading by the management system.
The Kilomux-2100 sub-rate multiservice multiplexer incorporates numerous test features for easy maintenance and rapid fault detection. Upon operation and during normal use, automatic self-test and link-test are performed, and all problems are reported to system management.
Local and remote loops can be performed for each main link and every I/O channel. A built-in BERT can be used for testing any I/O data channel and a built-in tone injection can be used for testing any voice channel. These extensive diagnostic tests ensure quick fault discovery and recovery.
