T1 card issue

[wfqk]

Hi we have T1 card inserted in router 2811. Show run command shows the t1 is like below:

interface Serial0/0/0
no ip address
shutdown

But other information shows it is like this:

card type t1 0 0

!

controller T1 0/0/0

framing esf

linecode b8zs

cablelength long 0db

channel-group 0 timeslots 1-24

My question is what is relation between the both? Thank you

[Masoud Pourshabanian]

Hello,

card type t1 0 0

Some cards support Both E1 and T1. Card type defines whether card operates in T1 mode or E1 mode.

After you specify your card type, you will see Controller T1 or E1.

Under controller T1or E1, you can specify your channel group. If your card has ability to be channelized, you can define several channel group(maximum 24 on T1 and 32 on E1  ).

Each channel group can include some time slots.

Each time slot gives you 64Kb.  24*64K=1.544 Mbps(T1)

Each channels group gives you an interface serial. In you example, you have only one channel group, grouping all time-slots(24), so you only have one interface serial.

You can define two or more channel groups.

channel-group 0 timeslots 1-12     12*64Kbps

channel-group 1 timeslots 13-24   12*64Kbps

You will have two serial interfaces with the bandwidth of 12*64K each.Remember you need to have the same configuration on other side.

Hope it helps,

Masoud

Thank you so much for your reply. Under the router, I cannot see any information about T1 or control T1 etc after inserting the t1 card. So what is wrong with the router? 

[Masoud Pourshabanian]

You need to first define your card type to be able to see controller and serial.

If you do not have card type, you need to upgrade or downgrade your IOS.

What is your card name and IOS version?

[Masoud Pourshabanian]

Give me the output of show version completely and also name of your T1 card to check the compatibility.

On the card, it has some sign, such as T1 DSU/CSU and

WIC 

1DSU-T1

v2

Do you think this card can send voice and can it be converted into layer one module?

[Masoud Pourshabanian · Accepted solution]

My previous comment was wrong. I edited when you posted your card name.

This card only supports T1. It is not channelized and it does not support PRI voice. It is end of sale.

"The T1 CSU/DSU WIC provides full or fractional T1 service. T1 CSU/DSU WIC does not do channelized T1 or ISDN Primary Rate Interface (PRI)."

VWIC3-1MFT-T1/E is a newer card supported on 2800 series.

This card supports channelized and also voice.

Check the link below.

the T1 cable can plug in this T1 card and work well? -- T1 DSU/CSU

I think this is newer one --VWIC3-1MFT-T1/E. what is the original T1 type in the past year?

[Masoud Pourshabanian]

You get a line from your service provider. You connect that line to a modem suggested by your service provider. Then connect your modem by a RJ45 to your router. IP Under interface serial  and encapsulation ppp or HDLC. It will work.

VWIC3-1MFT-T1/E is a popular card and commonly used for both E1 and T1 .

Do you see your T1 card information with "show version" command
