7206 to 3845 using E1 and/or Gigabit Ethernet

Unanswered Question
Feb 23rd, 2007

Trying to design a WAN to LAN connections. One of the part is to connect Cisco 7206VXR-NPE-G2 to Cisco 3845.

One option is to use E1 connection (as WAN), using Mix-Enabled T1/E1 Port Adapter (PA-MCX-2TE1) at the 7206 and 1 port T1/E1 Voice/WAN (VWIC2-1MFT-T1/E1).

The second option is to use Gigabit connection (as LAN), using GBIC-SX to GLC-SX-MM (Fiber) or using PA-GE to NM-1GE (Ethernet).

First question, is my choice of modules/PA correct? If so, I planned to have VoIP capability in the future, will they support it?

Last question, are these kind of product related questions allowed in here, or should I post this somewhere else? I am doing this as a design project, and if viable I might give my students a similar project case with real life product.

Thank you.

I have this problem too.

What kind of voice setup you are going to setup either call center kind of or Simple VOIP solution between branch to branch.

Please below - It will give you some idea.

See there is nothing, it very simple.

E1 will connect to your router...

configure following configurations

controller E1 0/3 (Slot you should know, where you are puting E1 MFT card)

framing NO-CRC4

channel-group 0 timeslots 1-31

Automatically one seriall interface pop up.

interface Serial0/3:0

description ### XXXXX XXXX XXXXX ###

bandwidth 2048

no ip address (You can put IP address, if not using multilink)

encapsulation ppp

no ip route-cache

load-interval 60

ppp multilink

multilink-group 1 (You can bind more than one link into Multilink and get aggregate bandwidth)

interface Multilink1

description ##### MultiLink #####

ip address {IP Add} {Subnet Mask}

load-interval 30

ppp multilink

multilink-group 1 (Should be match with Interface multilink no.)

( If you are not configuring more than one link .. Please ignore Multilink configuration and multilink command into serial interface.)

Now, router's ehthernet interface will terminate into PBX..

Now PBX GUY know to distribute Number expantion.

If any queries please revert.

Que:

1) MFT voice card required. VWIC2-2MFT-T1/E1

More information and question answer you can get from following link:

http://www.cisco.com/pcgi-bin/search/sr.pl?q=MFT%20cards&res=9&uid=&country=US&language=en&siteToSearch=cisco.com&filter=p&c_u=/en/US/products/ps5855/products_qanda_item0900aecd8028d2e5.shtml

2) Configuration already given you.

3) There is no any specific requirement for voice setup.

One another solution.... But thi is more flexible into call center setup.

You can connect router Fastethernet interface to 4510 Series switch and connect IP phones with the switch. With that IP phone, you can connect PC also.

You have to create two different VLAN, one for Voice and another for Data.

So, call center agent can use VOICE as well as Data from Signle.... Switch port.

Enjoy.....

If any queries please revert.
