RICiE 1 RICiT 1 Intelligent Converters for Fast

RICi-E 1, RICi-T 1 Intelligent Converters for Fast Ethernet over E 1/T 1 Product Update & Overview (Version 2. 10) Ethernet Access over PDH/SONET/SDH Solutions Updated: July 2007

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

Version 2. 10 • Generic Frame Procedure (GFP- G. 8040) • New HW: • Physical E 1/T 1 port changed to comply with RAD’s products RICi-4/8 E 1/T 1 and Egate-20 (swap of RX & TX lines in respect to the old HW) • Flow control support at 100 MHz master. ppt Slide 3

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 master. ppt Slide 4

Ordering option • RICI-E 1 replaces RICI-E 1/AC & RICI-E 1/48 • RICI-E 1/U replaces RICI-E 1/AC/U & RICI-E 1/48/U • RICI-T 1 replaces RICI-T 1/AC & RICI-T 1/48 • New option Hardened enclosure, resistant to extreme temperatures (-22 C to 70 C/7. 6° to 158°F) with 24 VDC power supply • RICI-E 1/24 • RICI-T 1/24/U • RICI-T 1/24 master. ppt Slide 5

Applications master. ppt Slide 6

Demarcation Point between the Carrier’s and Customer’s Networks • RICi-E 1/T 1 enables service providers and ISPs to supply transparent Ethernet services, without interfering with user traffic master. ppt Slide 7

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 E 1 or T 1 circuit by Ethernet traffic master. ppt Slide 8

RICi-E 1/T 1 General Overview master. ppt Slide 9

General • RICi-E 1/T 1 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 E 1 or T 1 • Bridges between a LAN interface and framed/unframed E 1 or T 1 interface master. ppt Slide 10

Physical • Network interfaces: • E 1 balanced RJ-45 • E 1 unbalanced BNC • T 1 balanced RJ-45 • User interface: • 10/100 Base. T (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 • 1 U half 19 inch box master. ppt Slide 11

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 – Configu. RAD – RADview‑Lite (SNMP) • Out-of-Band management: • ASCII terminal connected to control port master. ppt Slide 12

Bridge capabilities • Ethernet Bridge • Transparent/Filter mode: • MAC Learning and filtering is enabled/disabled • Qo. S: • four priorities according to: – VLAN priority bits (802. 1 p) – IP Precedence field • Enable/disable VLAN stacking (“double VLAN”) master. ppt Slide 13
