TDM

TDM over IP (TDMoIP) is the emulation of time-division multiplexing (TDM) over a packet-switched network (PSN). TDM refers to a T1, E1, T3 or E3 signal, while the PSN is based either on IP or MPLS or on raw Ethernet.

TDMoP is an approach that enables service providers to deliver legacy TDM services over a performance-grade packet network.

There are many devices to convert TDM traffic (E1, STM) to Ethernet Packet based infrastructure.

TDM over Ethernet  or TDM over IP

What is TDMoEth or TDM over IP?

    This technology is specifically beneficial when it comes to enabling the transport of TDM traffic over cell-based networks. So, call it TDM over IP, call it E1 to IP converter

Why Do we need it?

    The move from a TDM (time-division multiplexing) based network to an Ethernet or IP-based packet-switched network is one that is both gradual and necessary in order to improve performance and keep costs down. However, this switch is being approached in different ways depending on if the customer is a telecom carrier, utility, financial institution, or other industry.
 

    In all cases, legacy devices still need to be supported. TDMoE devices mitigate the risk of the transition by letting older TDM devices connect to the new IP-based network.  

USED CASE:
    

    Mobile backhaul involves the transport of data and voice signals across the back-end network to wherever it needs to go. In addition to standard voice communication, today's mobile phones demand data and access to the entire internet. In this case, their native TDM signals that travel across the mobile wireless network need to be converted into IP packets to travel across a packet-switched network that is either fiber-optic or electrical copper Ethernet.


What is its working mechanism?
    

    TDMoIP operates by segmenting, adapting and encapsulating the TDM traffic at PSN ingress and performing the inverse operations at PSN egress. Adaptation denotes mechanisms that modify the payload to enable its proper restoration at the PSN egress. By using proper adaptation, the TDM signaling and timing can be recovered, and a certain amount of packet loss can be accommodated. Encapsulation signifies placing the adapted payload into packets of the format required by the underlying PSN technology. For the MPLS case, ITU-T Recommendation Y.1413 contains a complete description of the packet format.


FEATURES:
- AN-TDM-IP-1E1 provides one E1 Port only, acts as transparent 1 port E1 to IP converter.
- Support Ethernet encapsulation and UDP/IP protocol encapsulation
- Support VLAN settings for E1 service and in-band VLAN management.
- Enough jitter buffer to resist packet delay variation (PDV)
- Local and remote E1 LOS and AIS and packet loss indication for troubleshooting and maintenance

Summarized one!

Why Do we need it?

• When move from a TDM based network to an Ethernet or IP-based packet-switched network to improve performance and keep costs down.  

• In legacy devices still need to be supported. TDMoE devices help TDM devices connect to the new IP-based network.
