requirements for 3G base stations. Each T1/E1 may be asynchronous should a service provider be backhauling
T1/E1s from multiple carriers.

A Metro Ethernet service module, shown in Figure 10, supporting T1/E1 ports is shown at the board level using
Zarlink’s CESoP processors. The service module consists of three line cards and an uplink card connected to a
packet backplane.
The first line card supports up to 32 T1/E1 lines, containing up to 1024 DS0, for Nx64 kbps structured data transfer
(SDT) CESoP connections. The T1/E1 lines are broken down into DS0 channels on an H.110 bus. The
ZL50110/11/14 establishes CESoP connections, with each connection taking a number of DS0 channels from the
H.110 bus.
The third line card support up to 32 T1/E1 or 2 T3/E3 lines for private line unstructured data transfer (UDT) CESoP
connections. The T1/E1 lines are not terminated on the card by are transparently packetized into individual CESoP
connections by the ZL50110/11/14.
The second line card support multiple 10/100/1000 Mbps Ethernet ports for native Internet, video and data service.
The uplink card multiplexes the Ethernet traffic from the three cards, and uplinks the CESoP, Internet, video and
data traffic to the packet switched network (PSN.)
