1. RICi-E1, RICi-T1 Intelligent Converters for Fast Ethernet over E1/T1 Product Update & Overview (Version 2.10) Ethernet Access over PDH/SONET/SDH Solutions Updated: July 2007

2. master.ppt Slide 2 What's new in the product?

3. master.ppt Slide 3 Version 2.10 Generic Frame Procedure (GFP- G.8040) New HW: Physical E1/T1 port changed to comply with RAD’s products RICi-4/8E1/T1 and Egate-20 (swap of RX & TX lines in respect to the old HW) Flow control support at 100MHz

4. master.ppt Slide 4 Generic Frame Procedure (GFP) Advantages Byte by byte transmission (unlike IMA & MLPPP): Reduced latency, for time-sensitive services Fixed overhead (unlike HDLC): Improved line utilization predictable throughput regardless of data transmitted Reduced packet re-transmission due to errors Frame delineation and synchronization mechanism based on GFP HEC field and not HDLC flag Error detection and correction (single & multiple) Robust protocol includes: CRC for GFP packet header field CRC for payload Standard protocol Allow interoperability between different vendors

5. master.ppt Slide 5 Ordering option RICI-E1 replaces RICI-E1/AC & RICI-E1/48 RICI-E1/U replaces RICI-E1/AC/U & RICI-E1/48/U RICI-T1 replaces RICI-T1/AC & RICI-T1/48 New option Hardened enclosure, resistant to extreme temperatures (-22C to 70C/7.6° to 158°F) with 24 VDC power supply RICI-E1/24 RICI-T1/24/U RICI-T1/24

6. master.ppt Slide 6 Applications

7. master.ppt Slide 7 Demarcation Point between the Carrier’s and Customer’s Networks RICi-E1/T1 enables service providers and ISPs to supply transparent Ethernet services, without interfering with user traffic

8. master.ppt Slide 8 Main Value Proposition Supports Generic Frame Protocol (GFP-G.8040): Allows connectivity with third party device Improves PDH link utilization Enables provision of transparent LAN services Secured user and management traffic Full utilization of E1 or T1 circuit by Ethernet traffic

9. master.ppt Slide 9 RICi-E1/T1 General Overview

10. master.ppt Slide 10 General RICi-E1/T1 is an Ethernet CLE (Customer-Located Equipment) Provides a demarcation point between the private LAN and the operator ’ s network Intelligent converter between Ethernet to E1 or T1 Bridges between a LAN interface and framed/unframed E1 or T1 interface

11. master.ppt Slide 11 Physical Network interfaces: E1 balanced RJ-45 E1 unbalanced BNC T1 balanced RJ-45 User interface: 10/100 BaseT (RJ-45) Half or full duplex. Auto negotiation DB-9 for local management Power Supply: Wide range power supply 100–240 VAC or -48/60 VDC 24 VDC for hardened option 1U half 19 inch box

12. master.ppt Slide 12 Management VLAN separation of management and user traffic: All packets with dedicated management VLAN will only be sent to the network port In-band management : Via the Ethernet port: –Telnet –ConfiguRAD –RADview ‑ Lite (SNMP) Out-of-Band management: ASCII terminal connected to control port

13. master.ppt Slide 13 Bridge capabilities Ethernet Bridge Transparent/Filter mode: MAC Learning and filtering is enabled/disabled QoS: four priorities according to: –VLAN priority bits (802.1p) –IP Precedence field Enable/disable VLAN stacking (“double VLAN”)
