What's new in the product?

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

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

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

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

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

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

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

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”)
