Cbilodeau: Creation
2009-12-30T14:38:28Z
<p>Creation</p>
<p><b>New page</b></p><div>TelcoBridges products supports 3 types of [[Line_Interface | line interfaces]] in 4 possible [[TDM_Module_Options | TDM modules]].<br />
<br />
<br />
== Redundancy ==<br />
<br />
=== <u>SONET/SDH</u> ===<br />
Only the [[SONET/SDH_interfaces | SONET/SDH interfaces]] have an innate redundancy feature. There are 2 ports per [[SONET/SDH_interfaces | SONET/SDH interfaces]] modules: Main and APS. In the eventuality where the Main fiber is damage or disconnected, the APS can take over and resume service.<br />
<br />
=== <u>Line Service Distribution</u> ===<br />
<br />
The DS3 and E1/J1/T1 interfaces doesn't have redundancy connectors. To minimize the effect of a [[Line_Interface | line interface]] failure, it is recommended to distribute groups of [[Line_Service | line services]] of each devices between providers when possible. This create share loading between devices and avoid overwhelming a system provider because all the traffic are redirected to a single device.<br />
<br />
==== <u>Recommended Setup</u> ====<br />
<br />
This is a recommended setup when using DS3, SCSI or RJ48 interfaces:<br />
