Hi Sami - 1. Yes, they support G.703 and G.704.
2. The dual-port E1 PIM has RJ-48 interfaces. The dual-port channelized E1/T1 has RJ48 as well. The dual-port synchronous serial has high-density serial interfaces as per on a Cisco router. For this module you need an external CSU/DSU 3. I would have thought that any RJ-48 to BNC balun would work. It needs to change the impedance from 120 ohm to 75 ohm - it doesn't do anything to the framing, so the following balun would work: http://www.blackbox.co.uk/solutions/display.asp?cs=dvh&id=1&doc=mt242a-m I think that's what we used. Even though it says it is a G.703 balun it should do G.704 as well. Cheers, A. ________________________________________ From: [EMAIL PROTECTED] [EMAIL PROTECTED] On Behalf Of Sami Ghourabi [EMAIL PROTECTED] Sent: 11 March 2008 15:44 To: [email protected] Subject: [j-nsp] Question about E1 interfaces in J2300 Hi list, I'm somewhat new to routing and Juniper Networks routers, so please tolerate my ignorance. I have some question about the fixed E1 interfaces in J2300 routers. 1. These interfaces are fractional interfaces supporting G703 and G704 protocols, am I right? 2. What is the connector type of these interfaces? I know that channelized E1 on Juniper have J48-S connectors, but I'am not sure about fixed fractional interfaces connector type for J series. 3. Are there E1 dual BNC balanced cables supported by these interfaces? As far as I know, Juniper doesn't provide this kind of cables. Did anyone used this kind of cables and which brand would are know to be compatible with Juniper routers ? Another question not related to E1 interfaces. Do J routers have any type of interfaces that can work in synchronous and asynchronous mode, not simultaneously of course. Thanks for your reply. Best regards. Sami. _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
