I can't seem to get this to work. I've tried various adapters (self-done) and I'm stuck. I have a 2502 and I don't have the rj-45 to db9 adapter, and I need to fabricate one. Does anyone know the pinout colors that will work with a Cisco 2502? I thought it was 1-red 5-black 6-green 9 -orange (on the db9 to rj45 adapter), but lately I've been thinking it might be: 1-green,5-black, 6-red, 9-orange Or perhaps I've got a bad db9 port on my 2502?

It works when it connects to servers/workstations that have rj-45 ports on their token ring cards, but not with my "home-made" rj-45 adapter for my Cisco router. Can anyone assist? Thanks in advance.

RE: Carrier Transitions : Any Comments [7:30829]
I have worked on the telco side and as you can imagine, this happens a bit.. At least you were working with the telco.. You don't know how many people would refuse to change anything.. Did the problem clear after telco testing or after you replaced the wire? That will tell you where the problem was.. I'm curious, how did you know the carrier transitions were within 24 hours? Had you experienced the bouncing and cleared the counters the previous day? If so, those were the only errors you received? For a T1, telco will usually run QRSS, 1's and 0's.. DDS, 2047, 1's and SP5.. More can be run of course but generally not, from my experience..

I got someone at the local office to telnet into the router, which was down/down, and the LMI was down/down, and there were just under 10 carrier transitions in the last 24 hours. I had them powercycle the router without any luck. I concluded that my provider was most likely the cause of the problem, and that it was at the branch office circuit, since my router here was talking fine with the other two remote offices, and my LMI was up/up. My provider told me that the circuit was bouncing, or in other words, it had been going down and back up several times since yesterday evening. After several hours, they did an out of service test, where they told me that it had tested dirty to the CSU but clean to the SmartJack, so they were going to put it on hold until I had replaced the WAN cable and reseated the WIC-1DSU-T1 card in the 1720 router. I went out to the branch office and did that, and the PVC has after I powered it on been up for about an hour now. My question now is: Is this (A) a normal thing that you suddenly have to reseat the WIC and/or replace the WAN cable, and that it can cause carrier transitions, or is this more likely (B) my provider that has found and corrected the error on their site, but now is trying to make it look like it was my equipment that was faulty, or (C) Thanks for any comments to this, Ole ~~~ Ole Drews Jensen Systems Network Manager CCNP, MCSE, MCP+I RWR Enterprises, Inc.

RE: Frame relay and dropped packets... [7:4529]
You need to look at multiple factors when checking for dropped traffic. You say forget DE and such but this is actually important when checking for this type of information. Discard Eligible packets are not guaranteed to cross the pvc. Do you know what your CIR rate is from your carrier? They only guarantee this amount.. If you send over this amount for an extended amount of time (which many customers do) then you can definitely lose traffic..

All you should really need from the carrier is the pvc information, and even then you should be able to see the local dlci's with inverse arp..

Some of you may think that the new version of Cisco IOS detects the LMI type automatically but I have seen this not happen on more then on occasion!

(I am curious as to how far they let me go with this). I know I need at least 1 more token ring, 2 bri interfaces.. Voice, ATM. I'm thinking: 2511 2620 with 2-port fxs int card 2610 with 2-port fxs int card - I'm wondering if these also need the Voice interface cards... 2504 - tokenring and BRI 2503 - BRI Catalyst 5000 or 2901 I was hoping to do ATM.. Maybe instead of the 2600's, use 3620 or 40 and add Single-port 155-mbps ATM OC-3 MNM to each with a Lightspeed 1010. (dreaming? I'm guessing the above modules will not be the optimal match.) 2 tokenring mau's.. We actually have 2 ISDN lines I hope to incorporate as well for the ISDN. Any criticism/help would be appreciated.

RE: O/T Digital Cross Connect
For the first question: Digital cross-connect systems (DCSs) have been used for several years to manage the digital DS0, DS1, and DS3 channels between switches--the intermachine trunks. Digital cross-connect systems provide a termination point for backbone trunks in the local and long distance network. A variety of DCS products can terminate DS1 and/or DS3 trunks, copper or fiber, and cross-connect channels within them. Through this cross-connect arrangement, end-to-end circuits can be established at speeds ranging from 2.4 Kbps to 44.736 Mbps. Using manual reconfiguration commands, circuits can be rerouted by establishing new cross-connect paths at one or more local or remote DCSs. DCSs are planned for deployment in the local loop to provide the same level of control for customer access circuits. In this case, customer access circuits would terminate on a central office DCS where individual data, voice, or video paths would be cross-connected to the appropriate local service equipment or intermachine trunk. DCS provides centralized operations, administration, management, and provisioning capabilities to the carrier. This includes facility and performance monitoring, loopback testing, and alarm generation and processing. Once a circuit is defined via cross-connected channels, the DCS is transparent to data flow. The DCS can be considered an electronic version of a manual patch panel. The DCS also can support a dual path capability between two DCSs. These self-healing services all function in the same manner. When a DS3, for example, enters a DCS, the signals it carries can be sent out on two separate transmission paths to their destination. At the destination DCS, the best signal is selected for delivery to the customer. A failure in one path will generate alarms, allowing repair and restoration to occur while customer service continues uninterrupted on the other path.

RE: Total number of CCNP's worldwide?
Someone just sent this on the 22nd Do you read the emails sent through groupstudy? I don't know if the numbers are correct but then again does it really matter?? Here is the email that was sent. Hi I spotted this on the alt.certification.cisco list this AM and thought I would forward it here since the question has been asked s many times. In a follow up post asking where he got these figures, his reply was from his network academy instructor.
