Could someone please explain what Fractional T1 via Frame Relay means? Which hardware support this?
Thanks

I believe that the configs that you post would be fine.
the NM-1CE1T1-PRI is for ISDN PRI. I do not see running Frame Relay over ISDN.

A fractional T1 is a serial link that operates at a fraction of full T1 rate (1.544Mb is full rate). A fractional T1 may operate with normal point to point encapsulations such as PPP or HDLC or it can operate with Frame Relay encapsulation.
So a fractional T1 via Frame Relay would be a serial link providing some fraction of 1.544 speed and using Frame Relay encapsulation. (connected to a Frame Relay service provider)

Rick,
And which hardware do I need to do this? Any T1 cards with 18xx/26xx/38xx routers?
Thanks!

A T1 card in any router should be able to do fractional T1 over Frame Relay.

If I use WIC-1DSU-T1-V2 with a 26xx router, are the following configs good?
interface Serial0/0
service-module t1 framing esf
service-module t1 linecode b8zs
service-module t1 timeslots 1-12 speed 64
service-module t1 data-coding normal
service-module t1 cablelength short 440ft
service-module t1 remote-loopback full
no ip address
encapsulation frame-relay IETF
frame-relay lmi-type cisco
interface Serial0/0.100
ip address 10.10.10.1 255.255.255.0
frame-relay interface-dlci 100
...
Does this card NM-1CE1T1-PRI work?
What are the advantages/disadvantages of channelized vs non-channelized given fractional T1 will be used?
Thanks a lot.
