COP series products are based on Circuit Emulation Services over Packets technology (CESoP). The idea is to "tunnel" a TDM circuit (e.g. E1/T1, or RS530, V.35 etc.) through a packet-switched network. The TDM equipment at either end is unaware that they are connected by anything other than a TDM network. The packet-switched network (IP network) is being used to emulate the behaviour of a TDM circuit.

Interfaces
Uplink: Fast or Gigabit Ethernet uplinks allow to connect COP products to service provider’s IP network. The transport uses either copper or fiberoptic connections
Service Link: Multiple copper based connections can be used to connect customer’s equipment such as traditional voice equipment, data switches, E1/T1 based GSM stations for wireless backhaul, or RS530, V.35 based equipment.

Manageability
COP Series products can be managed through standard based network management protocol such as SNMP, or using telnet with CLI menus. COP is also integrated into access system platform MACS and can be managed via centralized management SNMP or web GUI based “MACS View”.

Packaging
6U RA-U racks can be used for central service station (POP) deployment, with a density of up to 10 cards per 6U rack chassis, for up to 60 service interfaces. Stand-alone RA-T chassis is a convenient choice for deployment at customer premises.

Outstanding Features

1. Support various standard TDM tunneling technologies:

• Circuit Emulation Services over Packets (Draft – IETF)
• SATOP over Ethernet (Draft – IETF)
• TDM over IP (Draft – IETF)
• TDM over MPLS (ITU-T 1413/1414)
• Further standards (from e.g MEF, ITU-T)

2. Support single (according to 802.1q) and double VLAN-tagging (transparent for customer's VLAN-tags)

3. Support QoS in different layers of the OSI layer model:

• VLAN priority field
• MPLS label
• IP – Type of Service (TOS) and/or Differentiated Services (DSCP)

4. Completely protocol transparent for TDM data streams

5. Outstanding clock recovery mechanism meeting the following standards:
G.823 (E1), G.824 (T1), EN302 084 and EN300 462-3-6.Packet size configurable by changing the packetisation latency, e.g. @ 2.048kbps (unframed)

• 125ìs, 250ìs, 0.5ms and 1ms
• 32, 64, 128 and 256 (E1) bytes

Examples of Applications

Example 1:
Using COP-FE for Wireless Backhaul - Connecting GSM Base Stations for 2.5G to 4G Wireless Networks

Example 2:
The COP-FE with its port based double VLAN tagging and two separate line interfaces can transfer the data of different companies at the same time with security. The packets can be de-multiplexed at different sites

Example 3:
Radio Link Connectivity - Transmission of up to 4 x V.35 over radio link by cascading two COP-RS, with corresponding network based on Ethernet using COP-FE
