FAQs

Q: Does this module support NT mode?
A: No. It operates in TE mode only. For NT/TE selectable operation, use an NT/TE variant.

Q: Is it compatible with ISR G2 routers?
A: No. It is intended for ISR 4000 Series routers with NIM slots.

Q: Is an external NT1 required?
A: Yes when connecting to U-interface ISDN from the provider; the module presents an S/T TE interface.

Q: Are voice licenses required?
