Connectivity Overview |
|
|
The MediaBand-VX delivers a single X.21 or V.35 circuit transparently across a fibre link.
Pairs of MediaBands are required, but different versions can be used at each end,
opening a number of interesting conversion opportunities which are covered below.
The fibre presentation is via an SFP (Small Form Pluggable) socket into which most
standard SFP modules can be inserted, providing customers with the option and flexibility
to use different light sources for different fibres over different distances.
An RJ45 Ethernet port is fitted and this can be used to connect to a LAN to transport
Ethernet traffic across the fibre link, for example, or for management and Event/Alarm
reporting, or for cascading MediaBands together so multiple devices can use the same
fiber link. |
|
|
|
|
|
|
|
Interfaces |
|
|
A single X.21 or V.35 interface with DCE/DTE options
Speeds from 64kbps to 2.048Mbps
SFP cage with the appropriate SFP Module interconnects to a fibre at 10/100/1GE.
A local 10/100/1GE UTP Ethernet port for management
RJ12 serial management port
MediaBand can also be controlled/managed across the fibre link through its partner’s
LAN or serial connection
IEC connector for quality internal AC PSU (DC options available)
The MediaBand-VX can interface with the G.703 models, providing interface
conversion. |

Clocking and Clock Sources |
|
|
MediaBand can be easily configured via the GUI Manager to handle clocks in a
number of ways.
If no external clock is available, as in Diagram 1 below, one MediaBand can be
configured to be the clock Master (using its very accurate on-board oscillator) and its
partner will slave clock across the fibre link.
This method, as opposed to running both ends via their onboard oscillators, ensures
the clocks are always locked and there will be zero slips/hits due to clock drift. |
|
|
|
|
|
Diagram 1 |
|
|
 |
|
|
|
|
|
Diagram 2 illustrates a scenario where an external clock is available.
DCE versions present a female socket and provide clock, and DTE versions have a male plug and accept clock, |
|
|
 |
|
|
MediaBand passes the clock across the fibre link ensuring both ends are synchronised to the external clock source.
Diagram 3 shows an example where both customer devices have a master clock source. Each MediaBand can be configured to accept
this clock and crucially a buffer can be user set to handle any slight clock differences between the two sources. Once, again ensuring there
are no data losses.
All of these configuration parameters are configured, locally or remotely, via the intuitive graphical interface. |

Ethernet Port |
|
|
MediaBand-VX provides a copper UTP 10/100/1GE Ethernet port which can be used to transport user Ethernet traffic through
MediaBand and across the fibre, as shown in diagram 4.
This Ethernet port can also be used for centralised management of a particular unit or its partner at the other end of the fibre.
This means a single fibre link can transport a V.35/X.21 trunk PLUS Ethernet traffic. |
|
|
 |
|
|
Diagram 5 |
|
|
 |
|
|
The Ethernet port can also be used to cascade MediaBands, thereby getting maximum use from a single fibre path.
Support for packets up to 1632 bytes in size (10,240 bytes Mar 09). |
|
|
|
|
|
|
|
Rate Limiting |
|
|
Depending on Ethernet and fibre speeds, it is possible for the local LAN traffic, when using MediaBand’s ability to transport Ethernet across
the fibre, to swamp the fibre link to the detriment of the serial link.
MediaBand has a Rate Limiting feature which can “choke” the Ethernet traffic down to a configured speed, irrespective of the speed of the
connected Ethernet, ensuring delivery of the X.21/V.35 circuit. |

Management |

Overview |
|
|
MediaBand can be locally or remotely configured using Patapsco’s
easy-to-use high functionality DbManager GUI software.
DbLite is supplied free with each unit.
Optionally available are versions to support and give visibility of
many MediaBand units, consolidating control, configuration,
Events/Alarms and diagnostics via the LAN connection. It is
sophisticated but simple to use via an intuitive Graphical User
Interface (GUI) and can also generate SNMP Traps and Alarms.
The DbManager supplied with MediaBand (DbLite) allows control
and visibility of a single MediaBand at any one time. A document
identifying the differences between DbLite and the full versions of
DbManager is available.
An option to encrypt the management traffic across the packet
network is available, together with a key management/update
system.
Demonstration software is available which illustrates both the DbManager and the MediaBand features. Please ask for information. |

|
|
|
|
|
|
Configuration Changes |
|
|
Configuration changes on MediaBand are made via the
DbManager. All configurations can be stored on DbManager.
Installations require little or no expertise in the field as most
configurations (other than setting an IP address) can be performed
remotely.
Configurations are held in non-volatile memory. |
|
|
|
|
|
|
|
Management Tools |
|
|
A wide number of statistics are available for the E1/T1 circuit and
Ethernet port. |
|
|
|
|
|
All Alarms are reported back to the DbManager and presented in a
dedicated window with descriptor.
Events and Alarms are held within MediaBand for access via
DbManager.
A dry contact alarm relay is available in the RJ12 port.
Information and graphs showing clock movements over time. Shows
frequency stability and the status of the clock.
Loops can be placed on the TDM port in either direction and at the
Ethernet level.
MediaBand generates Ping/Trace Route and responds to Ping and
UDP Echo requests.
Internal test on power-up with results visible via DbManager. |
|
|
|
|
|
|
|
Software/Firmware Updates |
|
|
New software can be loaded via the DbManager to MediaBand
New software is loaded to the off-line sector of Flash and is
confirmed via a CRC. Users can switch to the new software at any
time. DbManager can load new versions to multiple MediaBands
simultaneously. |
