1 Overview
This chapter describes the RC1201-2GE16E1T1 in terms of features and networking
applications, including the following sections:
Introduction
Networking applications
Features
Delivery models
1.1 Introduction
As the 3G era is approaching, data services grow rapidly. Traditionally Time Division
Multiplex (TDM), based on circuit switching, is of inadequate bandwidth, low channel
multiplexing rate, and weak expansion, which can hardly meet requirements from data
services. The Packet Switched Network (PSN), based on packet switching, is of flexible
networking applications, high bandwidth, and low cost, which becomes trend of the Next
Generation Network (NGN).
However, a great number of TDM devices are still in service on the network, which are still
predominant and will be coexisting with the PSN permanently. As a result, Time Division
Multiplex over Packet (TDMoP) is introduced.
The RC1201-2GE16E1T1, a box cabinet of 1 U high and capable of being plugged with
subcards, is a TDMoP device developed by Raisecom and oriented for local aggregation for
circuit emulation services. With the following features, it can meet requirements from diverse
services:
Provide 2 uplink GE optical/electrical interfaces.
Provide 16 ways of E1/T1signals.
Support at most eight 10/100/1000 Mbit/s Ethernet electrical interfaces (provided by its
sub-cards).
Support E1/T1 and Ethernet concurrently.
Basic functions of the RC1201-2GE16E1T1 are to emulate TDM services, carry emulated
service packets through the PSN, and implement transparent transmission of TDM services on
the PSN.As a local device, it can cooperate with other TDMoP devices of Raisecom, such as
the RC1201-4FE4E1T1.

1.2 Networking applications
Oriented for the access aggregation layer of the network, the RC1201-2GE16E1T1 is of
modular design, small size, and high integration. In NGN construction, it expands the PSN to
the access end by providing reliable E1/T1 service access, high bandwidth Ethernet private
line access, and complete Operation, Administration, and Maintenance (OAM) functions.
Typical application scenarios for the RC1201-2GE16E1T1 include:
Key customer private line access
Multiplexing of multiple ways of voice and Ethernet services
1.2.1 Key customer private line access
As show in Figure 1-1, a private line customer's Headquarter and departments are located
separately. To ensure high security, the customer uses TDM devices for networking. When
being transmitted to the PSN MetropolitanAccess Network (MAN), TDM private line
services are emulated by TDMoP devices. The Headquarter and departments implement point
to multipoint communication under the conditions as below:
The Headquarter is connected to the PSN MAN through uplink GE interfaces of the
aggregation TDMoP device RC1201-2GE16E1T1.
The departments are connected to the PSN MAN through uplink GE interfaces of a
TDMoP device.
This networking application is used for Structure-Agnostic Time Division Multiplexing over
Packet (SAToP).
Figure 1-1 Networking with RC1201-2GE16E1T1 for key customer private line access
1.2.2 Multiplexing of multiple ways of voice and Ethernet services
As shown in Figure 1-2, to ensure high security, the customer communicates through TDM
interfaces. When the carrier does not deploy Synchronous Digital Hierarchy (SDH) network
but Ethernet MAN only,

Voice and Ethernet services of the customer are transmitted to the Ethernet MAN
together through TDMoP devices.
The voice service is transmitted to the Public Switched Telephone Network (PSTN) and
IP services are transmitted to the Internet through the aggregation TDMoP device
RC1201-2GE16E1T1.
This networking application is used for Circuit Emulation over Packet Switching Network
(CESoPSN) and Ethernet service access.

2GE16E1T1
1.3 Features
The RC1201-2GE16E1T1 supports multiple types of service and provides abundant features
to ensure service transmission of high quality and efficiency.
1.3.1 Service types
The RC1201-2GE16E1T1 supports the following types of service:
TDMoP service: E1/T1 service emulation
Ethernet service: VLAN, MAC address forwarding, basic and selective QinQ.
1.3.2 PSN types
The RC1201-2GE16E1T1 supports the following PSNs:
UDP/IP: IP carrier network
MPLS: Multi Protocol Label Switching (MPLS) carrier network
MEF: Metro Ethernet Forum (MEF) pure carrier network
1.3.3 Payload encapsualation types
The RC1201-2GE16E1T1 supports multiple payload encapsulation protocols to emulate data
of different TDM frame types, including:
SAToP

CESoPSN
1.3.4 Interface types
The RC1201-2GE16E1T1, an aggregation device, provides the following interface types:
8 RJ45 interfaces which can provide at most 16 ways of E1/T1 services
At most eight 10/100/1000 Mbit/s Ethernet electrical interfaces
2 uplink GE optical/electrical interfaces
SNMP management interface
Console interface
1.3.5 Clock synchronization and recovery mechanism
TDMoP services require precise clocks. The RC1201-2GE16E1T1 supports the following
clock synchronization modes:
Internal crystal oscillator
E1/T1 line recovery clock
Ethernet side recovery clock
1.3.6 OAM features
