Connectivity Overview |
|
|
|
The MediaBand-32 interfaces to 16 or 32 E1 or T1 circuits and delivers these clear
trunks transparently across a fibre link.
[V.35 and X.21 interfaces available Q4 ‘09]
Multiple units can be inter-connected to drive more E1/T1s over a single fibre link if
required.
A second fibre can be used to provide a backup link for resilience purposes. Switch-over
is automatic with appropriate Alarms.
MediaBands can also be inter-connected to distribute E1/T1s across a site on standard
CAT5E cabling.
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 available for connection to a LAN for both transportation of
Ethernet traffic over the fibre and for centralised management and Event/Alarm
reporting. |

E1 or T1 interfaces
RJ45 120 Ohm or 75 Ohm (user switchable) via converter cable
Full E1/T1 clear-channel
E1/T1 card supports up to 16 interfaces

A local 10/100/1GE UTP Ethernet port for transporting packetised traffic, for
management purposes or inter-linking MediaBands
RJ12 serial management port
MediaBand can also be controlled/managed remotely across the fibre link through its
partner’s LAN |
|

|

|
Clocking and Clock Sources |
|
|
|
MediaBand can be easily configured via the GUI Manager to clock or be clocked in a number of ways.
If no external clock is available, as in Diagram 2, one MediaBand can be configured to be the clock Master and will clock all of its
E1/T1 interfaces. On-board oscillators are very high-quality Enhanced TCXOs rated at around 0.15ppm. Its partner MediaBands 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.
MediaBand can alternatively pass a single master clock source, derived from an attached E1/T1, across the fibre link ensuring both
ends are synchronised to the provided clock source. Diagram 3 illustrates this scenario. Any E1/T1 port can be used as a clock source
and MediaBand can be configured to automatically switch to other interfaces to source clock should this Primary clock fail, thus ensuring
other circuits are maintained. |
|
|
|
Diagram 4 shows an example where both customer devices have a master clock source on a PRI. Each MediaBand can be configured to accept this clock and crucially a buffer handles any slight clock differences between the two sources, again ensuring there are no data losses.
|
|
|
Ethernet Port |
|
|
|
MediaBand-32 provides a 10/100/1GE Ethernet port. This can be used for Management of a particular unit or its partner at the
other end of the fibre.
This Ethernet port can also be used to transport user Ethernet traffic through MediaBand and across the fibre, as shown in Diagram 1
above. This means a single fibre link can transport an E1/T1 plus Ethernet traffic. Support for packets up to 10,240 bytes in size.
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 E1/T1.
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 E1/T1 circuit.
MediaBand Distribution
Additional MediaBand units can be conected via the Ethernet Ports. This facility enables the fibre link to be shared accross multiple remotely
located MediaBand units to increase the port count and/or allow for remote location. See diagram 5. This means, within the limits of
driving distances, E1/T1 ports can be located where needed, for example in different communications racks. |

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. 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 other versions is
available.
An option to encrypt the management traffic across the packet
network is available, together with a key management/update
system.
Configuration Changes
Configuration changes on MediaBand are made via the
DbManager. All configurations can be stored.
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.
Alarms/Events
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.
Clocks
The current active clock source is displayed in DB Manager.
Loop-Backs
Loops can be placed on the TDM port in either direction.
Pings
MediaBand generates Ping and responds to Ping and UDP Echo
requests.
Boot Test
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 code to multiple MediaBands
simultaneously. |
