V5.2 to SIP Gateway | SIP to V5.2 Gateway

V5.2 to SIP Gateway

We offer the gateway for upgrading telephone networks featuring multiple V5.2 interfaces.

There are 2 options for using this gateway based on tasks to be solved.

Option 1 is used when it is required to replace the TDM Switch with the SoftSwitch. If multiple subscriber nodes are connected to the TDM Switch over the V5.2 interface they can be switched to the SoftSwitch using the gateway as indicated on the following figure.

V5.2 to SIP Gateway Connection Diagram.

In this case the V5.2 interface disconnects from the TDM Switch and connects to the gateway that is connected to the SoftSwitch via the SIP data communications network.

Option 2 is used when it is required to connect VoIP subscribers from the local network to the PSTN number capacity. If the operator has the existing TDM Switch with free V5.2 interfaces the gateway on the TDM network side looks as the V5.2 subscriber node while on the IP network side it looks as the IP ATE where IP subscribers register (please see the figure).

PCB design servises

PCB Design

TERRATEL offers contract PCB layout design services.

To be competitive on current markets we use our multiple-year experience in PCB design for external customers in order to create the most comfortable conditions for highly effective cooperation including:

Design specification

• Circuit schematics (any format will apply).
• List of components containing links to the manufacturing documents (datasheets)
  and reference designators (any format will apply).

• PCB drawings specifying dimensions, configuration, mounting holes, connector and
  button locations, LED mount height, areas without traces, areas without components, areas with limited mount height etc. (any format will apply).
• Information specifying trace features i.e. the number of layers, parameters of circuit
  groups (differential pairs, clock signals, high-voltage circuits, power circuits etc.), components with high power dissipation etc.

Development environment

Main:

• Mentor Graphics DxDesigner
• Mentor Graphics Expedition PCB
• PADS

Additional:

• DownStream Technologies CAM 350 Gerber editor
• Polar Instruments Si9000 PCB Transmission Line Field Solver
• PCAD 200x Design Capture and PCB Layout

Terms and Cost of PCB Design

The standard term of designing a board is from 1 to 8 weeks depending on its complexity. The cost is based on time we spend working on the project and complexity of the project. By applying to TERRATEL you will be able to appreciate our short lead time and high quality of PCB Design. 

Experience tracing of Printed Circuit Boards

• Routing high-speed differential signals.
• Routing signals in compliance with EMI (electromagnetic interference) and EMC (electromagnetic compatibility) requirements.

• Pre-layout and post-layout signal integrity analysis.
• Use of BGA and micro-BGA with a large number of pins as well as use of FPGA, CPLD and DSP chips and microcontroller based chips.
• Calculating trace parameters for controlled impedance boards. Non-symmetric and differential impedance matching and control.
• Matched length designs.
• Manual and combined routing.
