M4300 SFP Port Trunking Issues
Hi Planning to get M4300 switches for pabx implementation for multi campus environment. So incoming trunk line are both PSTN and E1 PRI ISDN. We have few buildings that we need to connect via n...
Of course, yes.
Hi
Yes, we intend to use PSTN (two wire) and E1 (2 Mb). Customer current uses, 128 PSTN and 8 E1. This is a benchmark project as this is the 1st ever time client from this segment deploying 10G to interconnect. If we successfully complete this project without connectivity issues then we have close another 30 customers.
Yes, the buildings will be connected via LSZH 6 core Singlemode fiber link to each campus buildings from MAIN MDF. That is to say each building campus will have 6 core single mode fiber link. We plan to deploy the switches one at each building with Netgear 10G SGP module to establish 10 GbE links at at each building. We planned to deploy
- M4300-24X24F in MAIN MDF
- M4300-12X12F in 15 building campus
- M4300-8X8F in 1 building campus
- Transreceiver - AXM762
- DAC
Maximum distance between buildings are within 990 meters.
... the more confused I am. One one hand, you design a 10 Gb backbone (potentially a little bit a "thin" channel) over fibre. On the other hand, do you expect a two wire connection of an E1 or a POTS ging direct onto the switch to be tunneled? Or are these E1 and POTS on the IP-PABX and the IP-PABXes are to be linked up over the IP network? Assume it's the later one ... depending on the CODEC used fot the IP-PABX interlinks, wild calulating 64kb per POTS and the obvious 2048Mb for the eight E1, this does sum up 25Mb. Perfectly sufficient.
