Can an E1-F card interconnect with an E1-M card

An E1-F card can interconnect with an E1-M card in the following scenarios:
- The E1-M card works in E1 mode and the E1-F card works in unframed mode.
- The E1-M card works in CE1 mode and the E1-F card works in framed mode. In addition, the E1-M card creates only one channel set, and the timeslots that are bound to the channel on the E1-M card are the same as those on the E1-F card.
