Key Features & Benefits

• Software-Selectable T1/E1 Operation: Supports both T1 (ANSI T1.403, 1.544 Mbps) and E1 (ITU-T G.703, 2.048 Mbps) standards, configurable via software without requiring separate hardware.
• Built-In Channel Service Unit (CSU): Includes an integrated CSU, eliminating the need for a separate external CSU device and simplifying trunk termination.
• ISDN PRI Support: Provides ISDN Primary Rate Interface capability with 23 B-channel + 1 D-channel (T1) or 30 B-channel + 1 D-channel (E1) configurations.
• Flexible Framing and Line Coding: Supports D4, ESF, or CEPT framing, along with AMI, ZCS, B8ZS (T1) or HDB3 (E1) line coding options, ensuring broad compatibility with central office and tie trunk requirements.
• Bidirectional Echo Cancellation: Provides echo cancellation in both directions, along with A-law (E1) and μ-law (T1) gain control, ensuring clear voice quality.
• Fractional T1 Support: Supports fractional T1 configurations, providing flexibility for bandwidth-specific deployments.
• Built-In Diagnostic Testing: Includes a Bantam loopback jack for testing T1 or E1 circuits, along with an OIC DB 25-pin interface.
