Overview
DataBand “MUX-4” is designed to provide reliable and flexible
multiplexing and cross-connectivity between up to 4 channelised E1
or T1 circuits. |
|
|
|
|
 |
Use the Mux-4 to transport multiple fractional E1/T1 services across a single circuit. |
|
|
|
Any timeslot can be routed to any other timeslot on any interface.
DbManager is a high-quality intuitive GUI that connects to and
manages/monitors DataBand “MUX-4”; several versions are
available in addition to the free DbLite supplied and multiple units can
be monitored simultaneously.
All Patapsco products are designed and manufactured to the highest
standards and all are independently approved by European test
houses. |
|
|
|
|
|
|
|
Software-selectable clock source, using any interface or high-quality
internal clock with auto-switchover to secondary/tertiary clocks on
circuit/clock loss. The internal clock is accurate to +/- 1ppm.
There is an internal battery-backed real-time clock for Event Log timestamps
and debugging purposes and up to 5000 Events are held within the DataBand in NV
RAM on a FIFO basis. Events
can be reported
automatically to the locally attached
DbManager or
across the LAN. |
|
|
|
|
|
|
|
DbManager can also access
the logs and download them
when required. DbManager
writes all Events and Alarms
to a flat .csv file in real-time.
This file can be manipulated
by external tools to format
and extract information.
DataBand provides excellent
diagnostic and debug tools
with visibility of all routing
decisions taken across the
unit and loops can be set in
both directions.
Configuration is held in nonvolatile
FLASH memory (retained during power-off) and
downloadable to/from the DbManager. Configuration files can be
saved to a file on a PC.
New versions of software can be remotely uploaded to DataBand via
the DbManager. This is loaded to an off-line sector of FLASH and a
confirmation check-sum given. The operator can switch software
banks or revert to the original software at any time. If the DataBand is
unable to run from the new software, it will revert to the original. |

The DataBand “MUX-4” benefits from a wide range of approvals for
connection to leased lines. All Patapsco equipment is RoHS compliant. |

|
|
1 Interfaces
• 1.1 E1/T1 - 4 TDM ports.
Marked as ‘21’ ‘22’ ‘23’ and ‘24’
By default 21 and 23 are configured to be DTE (connect to
leased lines); 22 and 24 as DCE (connect to CPE)
The default configurations can be changed by the user but crossed
cables are necessary.
E1
RJ45 120Ohm balanced
G.704 HDB3 encoded
Auto-detect CRC4 or non- CRC4 framing
(Multiframe or Doubleframe)
Support of non-switched E1 and Fractional E1 services
T1
RJ45 100Ohm balanced
ESF or D4 Framing selectable
B8ZS or AMI Line code selectable
All ports are configured by the users as E1 or T1. Software option
available to mix and convert between E1 and T1 which includes
A-Law to μ-Law voice encoding conversion.
• 1.2 Control Ports
RJ11 Marked ‘Terminal’
Asynchronous 8 data, 1 stop bit no parity 19.2kbps to 115kbps
(auto-detect)
Password protected
Ethernet RJ45 Marked ‘LAN’ 10baseT or 100baseT
Password protected
2 LEDs
TDM x 4
Each TDM Interface has 2 associated LEDs
Upper LED - fl=synchronising to Layer 1; solid=Layer 2 established
Lower LED - fl=circuit establishing; solid=at least 1 64kbps channel
in place LAN ACT x 1 Activity on the LAN
LAN 100 x 1 Off = 10baseT operation; on = 100baseT
operation
3 Relay Protection
Interface pairs 21 to 22 and 23 to 24 are Power-Failure Relay
protected and will be connected together in the event of power
failure. This forms a metallic path between the two ports
