I am looking to find a CMTS that can send a very narrow downlink. We would like to send RF on 430-432Mhz down and 50.0 - 50.2 Uplink for Amateur Radio Data and voice system.
I see C2000WL-Fixed Wireless base station based on DOCSIS over Air (DoA)
Downstream features supported: QAM256, QAM64, QAM16 and QPSK
Bandwidth supported: 6MHz to 3.5MHz (to accommodate wireless channels)
Programmable symbol rates Downstream features supported:
• QAM256, QAM64, QAM16 and QPSK
Downstream per channel bit rate 10, 20, 27 and 38 Mbps
Can someone tell me if an Arris MTA (TM502G to be specific) will show the DHCP Offer in logging even if the offer is incorrect and the MTA won't accept it?
I have no problems assigning an IP to the modem and getting it online but, the MTA won't go online. I've confirmed the DHCP Discover and Offer via packet capture at the DNS server and on the CMTS. At this point, I don't see the Offer showing in the MTA's DHCP log though all four DHCP transactions for the modem show in that log.
I am doing the upgrade test. I don't know what the function of the co-signed cvc and manufacturer's cvc are. what is the difference between co-signed cvc and manufacturer's cvc? Thanks!
I'm working on implement a SIP Voice MTA service for my cable network, because my Voice provider works similar to Net2Phone, and need SIP provisioning.
My MTA are CISCO and ARRIS, my CMTS a cisco uBR7246VXR, and Have cisco CNR V 6.1.1.3 to provisioning.
My SIP server only requires:
- Username
- Password
- Port 5060
- SIP server: X.X.X.X
- RTP 12000 a 15000
Such an asterisk
I'm trying to set DOCSIS LB in my lab using Cisco CMTS ubr10k with SCE2 IOS.
My setup is running D3.0 with 3G60 line card and RFGW10.
Can someone send me some configuration example and some test scenario in order to check my setup?
I am interested in providing my customers Caller-ID via their Moto DCT STBs. We have our own VoIP softswitch and can provide any application the Caller-ID of an incoming call as needed. The problem is that we are lost on the video side and do not know how to get it to the STB.
The plant has a Moto NC 1500 and we already provide VOD. The VOD manufacturer is not knowledgeable on how to get Caller-ID.
Any advice, direction, contact or product in US or overseas would be greatly appreciated.
is someone using these models of cable modem??
I bought a pair for testing and they are not connecting...
FIrst was the downstream frequency, i use to have 561.25 than i change it to 561 and they start trying to connect.
They are obtained downstream signal then searches upstream takes a few minutes and then return to do the same.
I changed the upstream frequencies and does exactly the same.
Is there a special setting for make them work?
this is my actual frequencys configuration:
I have the updated firmware for Motorola SB5100 and SB5101. Can someone provide an example Docsis 2.0 Config File that directs the Cable Modems to upgrade their firmware?
Thought I wold share what I discovered this weekend.
If you have your plant maps in Autocad (i.e. dwg Files) Autodesk, the makers of Autocad have come out with a new tool. It is called http://www.autocadws.com
It allows you to place your DWG files over the top of a google map and allows access from a simple web browser (flash) Iphone, or android phone. It even allows editing of the DWG file in the program. Even Read-Only files can still be annotated.
