RC1201-4FE4E1T1 TDMoverIP Access Gateway

Ethernet interface

• 5 Ethernet ports, 4 for user side and one for network side
• Transparent Ethernet bridging
• User bandwidth profie by rate-limiting and VLAN fitering
• VLAN tagging and stacking (Q-in-Q)

TDM interface

• 4 E1 or T1 ports
• E1 balanced and unbalanced or T1 options
• G.703 unframed and G.704 framed modes
• CAS and CRC generation for E1 circuit

TDM payload type

• CESoPSN, SAToP, HDLC and AAL1

TDMoverIP for Pseudowire Emulation

• E1/T1 communication over Packet Switching Network
• Support both framed and unframed E1/T1
• Confiurable buffer compensation for network packet jitter
• Dedicated external clock injection port
• QoS support by ToS and VLAN per 802.1p and 802.1Q

TDMoverIP timing

• Adaptive: the clock is recovered from the Ethernet network side interface
• Internal: the master clock source for the TDM circuit is provided by internal crystal oscillator
• External: an external clock injection is provided for synchronization
• Loopback: the transmit clock is derived from the E1/T1 receiving clock

Ethernet switching functions

• VLAN creation, deletion and confiuration
• 3 port modes: access, tunnel and trunk
• Port isolation confiuration
• Link aggregation confiuration
• Port mirroring confiuration
• Per port bandwidth profie and rate limiting
• MAC address table management
• Up to 4 output queues
• QoS policy based on CoS and DSCP
• Ethernet port loopback detection
• ACL confiuration based on MAC
