master.ppt Slide 2
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

Applications
master.ppt Slide 6
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 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 E1 or T1 circuit by Ethernet traffic

RICi-E1/T1
General Overview
master.ppt Slide 9
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 10
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 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
– ConfiguRAD
– 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
• QoS:
•
four priorities according to:
– VLAN priority bits (802.1p)
– IP Precedence field
• Enable/disable VLAN stacking (“double VLAN”)
