Horsebridge products for backhaul, TDM over IP and ISDN over IP telecommunications equipment from Patapsco provide a vital migratory component for the move from TDM to Packet Networks.
The TDM units are designed to allow other types of traffic, including legacy synchronous systems, to make a simple migration to IP whilst retaining the proven installed DTE equipment and applications, but benefiting from an IP-based architecture.
Typical examples of this kind of equipment would be TDMs, mobile phone BTS cells. In fact most equipment with a T1/E1 full or fractional presentation, X.21 and V.35 devices or any unit that uses traditional leased lines.
Called Pseudo-Wires, TDM over IP or CESoIP (Circuit Emulation Services over IP), PacketBand delivers high-quality synchronous clocked services to all kinds of TDM over IP application, including voice where quality maybe a critical factor.
The ISDN over IP models within the PacketBand range support dynamically switched clock-locked ISDN clear-channel calls across and through IP networks. Any ISDN device in the world can be accessed via PacketBand.
Clear-channel ISDN over IP at customer sites is a new service pioneered by Patapsco. It opens the way for dial-up data services, such as videoconferencing, secure phones, G4 fax, encryptors, codecs, batch transfer, backup etc, to take advantage of low-cost IP networks.
The difference between a VoIP unit and PacketBand-ISDN is PacketBand delivers non-compressed ISDN "B" channels and these are clock-locked to the remote ISDN network. This means any ISDN equipment can use the service and because everything is synchronised, ISDN devices on the Packet Network can "break-out" into the real ISDN network by using a PacketBnad-ISDN as a "gateway", and they can also receive calls.
PacketBand can be a powerful tool to aid carriers who are "sun-setting" ISDN services. PacketBand can be supplied as an alternative delivery of ISDN over packet networks, yet still have all of the characteristics of the traditional exchange-delivered service.
PacketBand TDM-1 & TDM 4G
PacketBand-TDM-1 and TDM-4G use the latest technologies, systems and standards to deliver to the DTE equipment T1 and/or E1 full or fractional "leased lines" over a Packet Network.
The PacketBand-TDM-G Range supports up to 4 TDM presentations.
- TDM-1 - Single port TDM over IP E1/T1 platform
- TDM-4G - Up to 4 E1/T1 or fractional TDM over IP E1/T1 platform
The accuracy of clocks and clock recovery for the E1 and T1 circuits is at the very heart of the PacketBand range. Some applications, such as mobile cellular backhaul, require the clocks to be particularly accurate for and T1 and E1 over IP services and the PacketBand, provide excellent jitter handling capabilities and robust clock recovery systems should there be any problem on the Packet Network.
Able to deliver 1-4 T1/E1 full or fractional (structured) services, the PacketBand has a number of field-upgrade options together with Patapsco's carrier-proven and established DBManager system which provides remote access and a network-wide view of all PacketBands and the links between them.
The products are quick and easily install, with local and remote configuration options and centralised and distributed control and visibility of the whole network.

PacketBand TDM-4C
1 to 4 T1/E1ports with PDH or true plesiochronous clocking
The PacketBand TDM-4C is based upon the PacketBand-TDM-4G architecture but additionally has the ability to provide a true PDH clocking system where the Transmit (Tx) and Receive (Rx) clocks can work plesiochronous.
This means different clocks at each end of the TDM over IP or TDM over Ethernet link can be supported.
Although similar in basic functionality to the PacketBand-TDM-4G supporting 1, 2 or 4 E1/T1s, this model has some key differences:
- PDH/plesiochronous clocking
- All 4 ports' Tx and Rx can be clocked independently
- Slightly smaller chassis where 2 can be located into a 1U space
- Separate external clock port
- Standard with internal AC/DC power
- Standard with POE (Power over Ethernet)
- Unstructured E1 (G.703) and T1 only

PacketBand - Primary Rate ISDN
The PacketBand-ISDN units provide PRI connectivity for transparent clock-locked "B" channels across ethernet and IP networks. Any type of ISDN traffic can use PacketBand and it is particularly useful for data transfer where the equipment needs to run in a clocked or synchronous environment.
The PacketBand-ISDN-P Range supports up to 4 BRI presentations.
- PacketBand-ISDN-4P up to 4 PRI interfaces
- PacketBand-ISDN-1P has a single BRI interface
The PacketBand-ISDN-1P is based on the same architecture and design as the PacketBand-ISDN-4 , but supports just a single T1/E1 PRI.
Please note that the PacketBand-ISDN-4P can be purchased with a single PRI interface enabled with the ability to remotely upgrade to more.
The key differences are that the single port PacketBand-ISDN-1P unit is slightly lower cost than the starter model ISDN-4P with a single PRI enabled. The PacketBand-ISDN-4P also supports non-switched TDM over IP point-to-point Pseudo-Wires as well

PacketBand ISDN-BRI
1 to 8 (NT or TE) ports for Basic Rate ISDN over I P
Clear-channel Basic Rate ISDN switched calls for BRI
over Packet Networks. Deliver uncompressed clock locked
channels for data and voice applications.
The PacketBand-ISDN-B Range supports
up to 8 BRI presentations.
- PacketBand-ISDN-8B
up to 8BRI interfaces
- PacketBand-ISDN-4B up to 4BRI interfaces
- PacketBand-ISDN-1B has a single BRI interface
The unit’s BRI ports are available as “NT” (looks like a
network and connect to local ISDN devices) and
“TE” (looks like ISDN devices and connects to an ISDN
network) in a number of combinations.
The NT interfaces typically connect to local ISDN BRI
devices whereas the TE presentation is normally to a “real”
ISDN network. PacketBand access to the real ISDN
network means devices on the Packet Network can use this“gateway” to dial equipment anywhere in the world via
ISDN. Equally, remote ISDN equipment can, with the
correct authorisation, dial into equipment across the Packet
Network.
Able to recover clocks very accurately across the Packet
Network, PacketBand delivers a very stable clock to
attached devices. In effect, all attached devices are locked
to a common clock and all are clocked very accurately
with no slips or packet loss due to clocks or PacketBand.
The clock synchronisation means accurate
communications across the Packet Network enabling all
types of ISDN equipment to communicate reliably and
also makes the ISDN break-in/out possible.
Devices and applications that need to work in a
synchronous environment will work successfully with
PacketBand. This includes encryptors, codecs, video and
secure phones.
The PacketBand will dynamically place calls across/through the
Packet Network in response to dialing by the ISDN terminal
equipment.
Calls to different locations can be made simultaneously, and any
combination of out-going and in-coming calls.
Calls can be placed via internal routing tables (with Primary/
Secondary/tertiary options for resilience) or using a recently released
SIP server option which centralises all routing and
configuration.
PacketBand also supports advanced features such as number
translation/manipulation.
The unit inter-works with other PacketBand products, not only
ISDN versions, but uniquely PacketBand can inter-connect
dissimilar devices so, for example, a BRI device can connect via
PacketBand, across and IP network to a V.35 piece of
equipment.
Key features:
- Clock-recovered capabilities like all PacketBands
- Suitable for all types of data, including synchronous
- Inter-works with other members of the PacketBand
family
- Up to 8 BRIs supporting “S” 4-wire NT presentation dependant upon model
- Support for ETSI (Euro) and ANSI (USA) protocols
- Conversion between ANSI and ETSI
- Tone generation
- Number translation/conversion options
- Separate ISDN “B” channels can call different
destinations
- In-coming/out-going calls in either direction
- Internal AC PSU 110/240V auto-sensing
- Optional alternate internal DC 12-48V supply
- Easy to configure via the established DbManager GUI
