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.
Hi
Sorry my fault i should have explained better. My bad, sorry
1. E1 ISDN / PSTN will not connect directly to Netgear switches.
2. Instead E1 ISDN/PSTN will connect to iP Pabx directly. So pabx modules/gateways/slot cards will be connected to Netgear switch via RJ45 cable.
3. The aim is, Pabx to do the signalling while netgear switch to carry that signals.
4. So the link will be established between main building and campus building via fiber cable thru interconnecting netgear switches.
See attached diagram and also pdf file as attached. both convey same thing.
Ok, then your set-up does make perfect sense. Are there plans to use the same network for data and voice?
Hi
The pabx system will also operate UCS (Unified Communications) which carry data to desktop to few (around 50) PC's for contact center operators. So yes, the switch should able to segment voice and data. Large part of it will be voice. To do this, possible to create Vlans to segment it?
