Description

Dual-port channelized T1/E1 interface for routers, combining ISDN PRI and fractional data on each port. Configure each port independently for T1 or E1, leverage the integrated CSU/DSU for line build-out and clocking, and terminate voice PRI trunks or NxDS0 circuits. Standards-based framing/coding over RJ-48C ensures easy interop with telco and PBX environments. Ideal for multi-trunk voice gateways and branch WAN aggregation.

Features

- Two independently configurable T1/E1 ports for flexible deployments
- ISDN PRI and channelized data on each port
- Integrated CSU/DSU simplifies wiring and reduces cost
- Standards-compliant framing and coding for carrier interop
- RJ-48C interfaces for direct telco demarc connections

FAQs

Q: Are the two ports independently configurable?
A: Yes. Each port can be set to T1 or E1 and configured for PRI or channelized data.

Q: Does it support ISDN PRI on both ports simultaneously?
A: Yes, both ports support ISDN PRI (subject to router performance and IOS).

Q: Is an external CSU/DSU needed?
A: No. The module includes an integrated CSU/DSU on each port.

Q: Can I use fractional NxDS0 data circuits?
A: Yes. You can allocate any subset of timeslots (1–24 for T1, 1–31 for E1).

Q: What connector type is used?
A: RJ-48C on each port, using 100Ω (T1) or 120Ω (E1) twisted pair.
