SUBRATE MULTISERVICE MULTIPLEXERS

Database

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.

Diagnostics

The Kilomux 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.

Compact chassis models

For applications requiring a small number of I/O

channels, the compact Kilomux-2104 model is

available. This modular unit, packaged in a

1U-high enclosure, supports four I/O modules. It

accommodates up to 16 asynchronous data

channels, up to eight synchronous data channels,

or up to 32 analog/60 digital voice or fax channels

over a single link interface. The Kilomux-2104 is

fully compatible with the Kilomux-2100.

KVF.6

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 supports 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.

KVF.8

Voice/fax low bit rate module uses the

G.723.1 digitizing technique to provide toll-

quality voice at 6.4 kbps for eight analog

channels. The card can digitize voice at rates

from 4.8 kbps to 16 kbps and supports inband

transparent fax transmission rates of up

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.

Interworking module

KMBE

Ethernet IP/IPX router/bridge module

supports the connection of up to 256 remote

workstations to a 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 features such

as Single IP, Solid Firewall™ and RADview SNMP

management.

Management options

The Kilomux offers three management options:

• ASCII terminal – an ASCII terminal can be

connected locally or remotely, using a dial-up

modem.

• Telnet – a Telnet client can be used to

control the Kilomux via its Ethernet

management port or via an inband

management channel.

• RADview management station – enables

complete monitoring and control from a

central management station. RADview

provides direct online supervision,

configuration and diagnostics.

The Kilomux devices include an SNMP agent and

can be managed using RADview-EMS graphical

user interface (on a UNIX platform). This

provides terminal access to remote devices from

any management station on the network for

configuration and troubleshooting.

Online supervision

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.

Sanity check

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.

Manual timeslot allocation and bypass

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.
