Telephony Interface Modules

Mix-and-match hardware modules give you a wide variety of interface choices: T1, E1, PRI, and POTS. Modules can be configured as follows:

• Two digital interfaces: software configurable as T1 or E1, Robbed-bit or CAS signaling, North American or Euro ISDN PRI protocol, NT (network) or TE (terminal equipment) simulation
• 8, 16, or 24 analog ports: FXS (network) or FXO (CPE)
• Combined digital and analog in a single unit (click here for details)
