DS1 Bit Rate issue 1

[111101001101001]

This is probably a daft issue ive overlooked but...

Im setting up a new pbx ( 2 x 8720 and 2 x G650) and when im adding a ds1 to connect to a UK ISDN30 the defauly bit rate is 1.544 and im trying to change the bit rate to 2.048 and its saying "2.048 Bit Rate is incompatible with DS1 circuit pack strapping"

Ive tried changing the line coding and framing but this isnt helping.

If you are using a TN464 card, don't forget to change the dip switches on the card to E1 configurations.
