The Loop-IP6510 Router/Bridge provides remote bridge connectivity from 4 Ethernet ports to 2 fixed WAN ports and also to 2 optional WAN slots. Whereas the 2 fixed WAN ports are always Ethernet, choices are available for the 2 optional WAN slots. Each of the 2 optional slots can accept one of 4 choices of plug-in cards, which are

(a) a card with dual T1 port

(b) a card with dual E1 port

(c) a card with one 10/100 BaseT fast Ethernet port

(d) a card with one SFP (mini-GBIC) housing for 100M-FX fast Ethernet port

Using the optional dual E1/T1 card, up to 4 E1/T1 lines can be used for WAN connectivity, either separately or in a single bundle.

All Ethernet, WAN, and LAN ports have speed auto-sensing, half/full duplex auto-negotiation, and auto MDI/MDI-X crossover features. All serial (E1/T1) WAN interfaces support PPP, MLPPP, Frame Relay, Cisco-compatible HDLC and HDLC protocols.

The Loop-IP6510 Router/Bridge has a DB9S console port, which allows users to execute in-service diagnostics and fault isolation from a local terminal. It also allows users to manage remotely via Telnet, SSH and SNMP through Ethernet or WAN ports. Multicolor LED indicators and an ACO (Alarm Cut Off) button are provided on the front panel.
