What is the maximum number of direct lines that can be configured on an E1. When I try to configure translation rules, it does not take more than the 15th translation. Please help.

There is no limit defined in the software. You could have as many DID's as the carrier can associate with the E1.

The IOS software does indeed have a maximum of 15 translation rules. If each DID is being translated and more rules are needed, alternatives might include:

1. Making the translation rules sufficiently generic as to allow them to transform a range of DIDs, as opposed to having a specific rule for each transformation.

2. Performing the translations in CUCM (if one is involved) using translation patterns

I hope this helps.
