Re: [c-nsp] Performance Difference NM-16ESW-1GIG and NME-16ES-1GIG
Le 23 sept. 2010 à 11:32, Jeffrey Denton a écrit : Looking at getting a couple of 3945s. NM-16ESW-1GIG is being recommended by one of my colleagues. He prefers the easy of use, not having to session in to the module. It's been pointed out that the router IOS will have to devote some of it's time to the module and perform the switching functions. We would have to get the 3945 as the module is not supported in the 3945E. The NME-16ES-1GIG is of course a newer generation. The module runs it's own IOS image. PoE is not a requirement. Links to the data sheets: http://www.cisco.com/en/US/prod/collateral/routers/ps259/product_data_sheet09186a00801aca3e.html http://www.cisco.com/en/US/prod/collateral/routers/ps5855/product_data_sheet0900aecd8028d15f.html How much does the older module affect the performance of the router itself when compared to the newer module?

This may seem obvious to anyone who has done this before but may be worth mentioning... The DS-3 signal operates uses a separate co-axial cable for each direction of transmission, so you will want a dual 734-type cable (two BNC connectors on each end, two physical co-ax cables.) The usual clocking, framing, etc. issues that apply to T-1 and other serial links apply. Exactly one clock source, framing must match on both ends, etc. Generally, C-bit is used for data pipes, M13 for T1s muxed up to T3. For fractional, you may have to work with your carrier for CSU-type settings and the like, but this is all configurable on the Cisco gear. Some carriers configure the CSU to make the pipe fractional and others just limit the throughput in software and leave the physical media at the full line rate. -- Jay Hennigan - CCIE #7880 - Network Engineering - j...@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
Re: [c-nsp] DS3 Nubie
One time I ordered a internet DS3 from ATT (prior to merger with SBC), I asked the rep about the order confirmation because it said ATM and I specifically said no ATM when we signed the contract. Rep said it's not ATM and don't worry. It got installed and it was ATM circuit. I complained and they gave us a free router and ATM DS3 card. (I forgot what router it was but it was probably pretty expensive back then) I never had problems with other carriers like that though. If you don't make DS3 cable often, I will recommend have a vendor make one for you. You may also want to buy or be ready to buy couple attenuators. At one location, the Telco equipment was sending out signal that was too hot for the DS3 interface and I had to attenuate it quite a bit. Telco would not lower the output for us.

Re: [c-nsp] DS3 Nubie
Assuming that the DS-3 order is non-ATM (likely unless you asked for ATM), this set-up should work just fine. For the physical connection. Please keep in mind the software needs (routing protocols and router table size) in considering the equipment to ensure it will meet your needs. ___ Brian Johnson Converged Network Engineer (CCNP, ENA) () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments -Original Message- From: cisco-nsp-boun...@puck.nether.net [mailto:cisco-nsp- boun...@puck.nether.net] On Behalf Of Jeff Wojciechowski Sent: Friday, September 24, 2010 1:57 PM To: cisco-nsp@puck.nether.net Subject: [c-nsp] DS3 Nubie All: We are considering upgrading one of our circuits to a fractional DS3 and would just like query the experts on the list to make sure that I have all my bases covered here if we go down the DS3 route as I have never touched DS3 before... I am considering using the following equipment: 3925 Router + NM-1T3/E3 + SM-NM-ADPTR (per http://www.cisco.com/en/US/prod/collateral/modules/ps2797/ps4909/prod uct_data_sheet09186a008010fba2_ps282_Products_Data_Sheet.html) That part seems pretty straightforward (but please correct me if I am wrong). Can I safely assume that since the carriers proposal doesn't mention ATM that I don't need NM-1A-T3/E3? Then from DMARC to my router I need to use 734 type cable with 75 Ohm BNC connectors (per tread from yesterday). Am I missing anything?

Re: [c-nsp] DS3 Nubie
Typically you want to ensure that you can do scrambling with what ever card you use. Typical setup is a card with a built in CSU/DSU and enable kentrox scrambling...
