I have a 2600 with a PRI card, when I try to do an isdn test call int s1/0:23 ######### the debug constantly comes back with "Cause i = 0x83E020 - Mandatory information element missing" Vendor states he doesn't see the SDN 'flag' coming through. I have both the isdn nsf-service, and the dialer map configured to use a class with the outgoing sdn command.

I have a Cisco SG300 switch on which trunks are configured. I have a server which sits on the switch via a trunk link of four network cables (4 Gbps total)on which LACP is enabled. I'm having trouble connecting to the server using VNC from a computer on the network. It doesn't happen all the time though, it's just random.
On looking at the logs of the switch, I saw something unusual. The trunk that connects the switch to the server is constantly removing all the member ports and adding them back again after a few minutes interval. That causes the trunk link to flip on and off all the time. What could be the reason that's causing it to happen? I know it could be the network cable but I'm using brand new cables and the server also is brand new.
I have a Cisco 8510msr that is connected back to back with a 7206vxr across a 155Meg connection.I receive lots of Output drops on the 7206vxr interface facing the atm switch. When I do the following command:-

My question is that cisco website says there are two type of cable connections for this type of config --which are --T1 CSU/DSU ConfigurationSet one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.Four-Wire 56k CSU/DSU Configuration For my network connection which type of config i should use??Secondly i try to connect these ports by normal crossover cable it did not work.So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.I check cable from ebay which is RJ45 RJ48 cross over -- will this cable work in my router to router connection.

I searched a lot but couldnt find a clear document about connecting 2 G.SHDSL routers back to back.First of all I am not sure which type of cable (RJ11) is used for connecting two 878 routers. Does it have to be cross or straight cable.
Which RJ11 pairs will be connected each other [code]
According the configuration samples One router must be CPE and the other must be CO for simulating DSLAM.
I'm having some trouble getting two Cisco 888's to work correctly back to back.. The two routers will ultimately be used in conjunction with a BT EPS8 circuit which is effectively four wires short distance between customer sites. We have configured lots of these using the older Cisco 878's.
Anyway, as i've been struggling to get line sync on site I've gone back to basics and connected the two 888's back to back. However, I've found that no matter what I do I can only get the routers to sync at 384kbps!? And that's with a one meter RJ11-RJ11 cable.. Very strange. When we've used the 878's we get much more bandwidth. I have tried statically assigning the line rate at both ends but it still only works at 384kbps.
I am setting up my lab using two 2901 routers which is running on 15.2 IOS.I am trying to simulate a back to back BRI.BRI Module: WIC-1B-S/T-V3 (x2) one of each router.
I followed this amazing document to understand the concept of BRI and configuration. url..but it never says if i can use the module that i have mentioned.
Q1. What cabling i need to use to setup back to back BRI using 2x 2901 routers with these modules?
Q2. What cabling do i need to use.
Q3. Is it actually possible to use these 2 modules alone to simulate a back to back BRI..?

I have given the questions with answers provided by the TELCO. I am also providing the running configuration of the PRI interface and also the error message i am getting when trying to test call itself.
1. Is the PBX designed for Pre-National or NI-2 protocol? -
Protocol using C7MATL
2. Are there any DID station numbers that your CPE cannot accept? -
No
(i.e. 0 or 9 in the 4th position)
3. Which carriers will be your choices for your PIC and LPIC? -

I'm trying to configure 2 routers (cisco 886) to create a link between them via ISDN link (in france) but it doesn't work
I think I put a base conf but nothing work :

I have a Cisco 2800 series router with E1 PRI module at Head Office,and Cisco 786 with single ISDN BRI port,When I dial from either side only one B channel is up ,means 64 K only.
View 1 Replies View RelatedI have a problem with ISDN BRI-1B-S/T-V3. In the documentation I read: "The ability to add BRI connectivity via a WLC lets administrators maximize valuable slot space while it provides additional connectivity options, such as Ethernet, on the same module." Does it mean that I can plug in the module Ethernet and it will work? I ask, because i have CISCO 1571-V router with this isdn module, i get the internet from Ethernet, and i wonder is there any possibility to use this module as WAN.

Would 256K or 128K Up and Down be enough for playing FPS games on xbox live? I cant find any ISDN modems that are new. Only used ones on ebay that I dont know would work on windows 7.
View 1 Replies View RelatedBoth of these ISDNs are up, this gives us 4 channels. Someone said they recieved a busy tone when they attempted to dial out. I looked over the system and seen there are two outbound pots dial-peers. Each dial-peer references one of the BRI ports. The preferences are the same on each dial-peer. I think what is happening is that the system is randomly selecting one of the dial-peers due to the preference, even if both channels of the BRI are in use. How does the system know if that port has both channels in use? I've not used ISDN before, so tried to enter the B-channel sub interface and the system (UC500) tells me I cannot do this. I was thinking about adding each channel into a trunk group and then referencing the trunk group in the dial-peer. I can obviously add both BRI's into one trunk group.

I am trying to move my ISDN dialup branches authentication/authorization from old ACS 4.1 to ISE appliance. Before it was through ACS 4.2 with TACACS protocol but now since we are moving to ISE we are moving them to ISE with radius.
Problem is that isdn client gets authenticated and authorized but calls get dropped and they dont able to communicate with HO. IP address is assigned by Head End router to all remote isdn dialing branches..
I have used default "PermitAccess" in authorization policy and authentication policy is also default. I dont understand where I am going wrong as authentication and authorization is sucessful.

aaa authentication network default group radius
aaa accounting network default start-stop group radius

I will install in the next days a 886VA router (VDSL over ISDN using PPoE). Since I have no possibility to verify the VDSL config, this is what i prepared. Is this config OK (only VDSL part) ?

For VDSL over ISDN the interface Ethernet0 must be used instead of ATM . Is this config correct ?
our client are using PSTN (modem) and is dialing up to our ftp box which is using ISDN (TA). according to them, they not facing any problem to dial up to other vendor which is using the same network infra (PSTN to ISDN). but, unfortunately in wont happen in my case which they (client) keep receiving the busy tone when they dialing to our ISDN no. i've set in our TA to accept both digital and analog calls and i'm using the DSS1 protocol which been told by our line provider.

View 6 Replies View RelatedI have configured Cisco 2811 and 3825 routers to connect the main and remote sites as per the attached topology. At the main site, the Cisco 3825 router is equipped with SFP ports (HWIC-1GE-SFP with GLC-LH-SM=) for fiber optic connectivity and also has a HWIC-1CE1T1-PRI installed The Cisco 2811 routers at the remote sites are each equipped with a WIC-1SHDSL-V3 module for SHDSL connectivity and with a WIC-1B-S/T-V3 for backup ISDN connectitivty.
In normal time the routers are using the SHDSL to Fiber optic connectitivty for communication. This has already been configured and is working. Now, there is a need to implement a backup connection between these sites such that in case the SHDSL or fiber optic connectivity fails, the routers should automatically dial up the backup ISDN connectivity so as to ensure business continuity.
