RICi-E1, RICi-T1Intelligent Converters for Fast Ethernet over E1/T1 Product Update & Overview (Version 2.10) Ethernet Access over PDH/SONET/SDH Solutions Updated: July 2007
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
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
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 (-22C to 70C/7.6° to 158°F) with 24 VDC power supply • RICI-E1/24 • RICI-T1/24/U • RICI-T1/24
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
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
RICi-E1/T1 General Overview
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
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
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
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”)
