Product Overview
'VCL-E1oP' E1 over Packet (8 E1 Port IEEE-1588v2 Version) TDM over IP / Ethernet equipment supports transmission of up to 8 x E1 links over IP / Ethernet, MEF or MPLS networks and synchronization using IEEE-1588v2 protocol.
The 'VCL-E1oP' E1 over Packet (8 E1 Port IEEE-1588 Version) TDM over IP / Ethernet equipment with IEEE-1588 protocol engine which provides a highly reliable clock recovery mechanism for extremely low jitter and wander control, even under variable network conditions.
8 x E1 Port E1oP (E1 over Packet) TDM over IP equipment provides 4 x GigE electrical ports along with 4 x Gigabit optical ports (out of which the user may select and use any 4 ports) to implement 1+1 add-drop (Drop-Insert), Ethernet link redundancy (Rapid Spanning Tree Protocol and Ethernet Port Trunking) and QoS by implementing 802.1Q based VLAN, Differentiated Services (Diffserv / DSCP), Port based Priority and 802.1p packet priority classification protocols for network optimization.
The 'VCL-E1oP' E1 over Packet (8 E1 Port IEEE-1588 Version) TDM over IP equipment also optimizes on the network usage, such that the bandwidth used by the E1oP equipment on the packet network is limited to the corresponding to the number of E1 ports and the time-slots that are being transported over the Ethernet / packet network.
How the TDM over Packet (8 E1 Port IEEE-1588 Version) equipment works
E1 data streams received on the E1 interfaces are converted by the E1oP engine of the E1oP equipment to Ethernet data packets (of a fixed size) and transported over the Ethernet network with UDP / IP, MEF or MPLS headers. At the receiving end the E1oP reconstructs the original data streams by removing the IP, MEF or MPLS headers and converts the Ethernet data packets back to E1 frames using highly reliable and accurate clock recovery mechanism. The 'VCL-E1oP’ (8 E1 Port IEEE-1588 Version) offers the user a choice of standard, E1 to packet and packet to E1 conversion that include SAToP and CESoPSN technologies. IEEE-1588 packet synchronization mechanism provides frequency and time-of-day synchronization for all points of the network to a common, single (GPS) source.
Key Highlights:
- Under 4ms latency on the E1 / T1 channels
- IEEE-1588v2 Clock Recovery (SECLK)
- Synchronize ToD (Time of Day) and Frequency of all nodes to a centralized / common GPS Receiver
- Synchronization to an External Clock (ECLK)
- Automatic clock priority selection with fall back
- Jitter and Wander conforms to and exceeds G.823 / G.824 and G.8261 and TDM specifications
- Password Protection
- Supports SSH and Radius for access control.
- The 8 x E1 over Ethernet (VCL-E1oP) multiplexer may be used to provide legacy TDM services over Gigabit Ethernet optical fiber, or wireless Ethernet/IP networks.
