Installation PTN-2-C37.94 with E1/PTN-2-C37.94 with T1 

11 

Release 01 02/2018 

In Figure 5 below, a more detailed functional setup is shown.  A LAN1 network interfaces the 
Dragon PTN node via the E1/T1 ports on the 2-C37.94 module.  The 2-C37.94 converts this 
traffic  into  Ethernet  traffic  on  the  backplane.  The  Central  Switching  Module  (=CSM310-A) 
converts this Ethernet traffic into packetized E1/T1 MPLS-TP and transmits it via an Ethernet 
IFM (e.g. 4-GC-LW) onto the Dragon PTN MPLS-TP network. The packetizing of C37.94/E1/T1 
occurs via CES: SAToP (see §2.2.6) or CES: CESoPSN (see §2.2.7) technique. 

The CES is normally configured between two ports of the same type (between two C37.94 
ports,  two  E1  or  two  T1  ports).  Via  the  CES:  CESoPSN,  it  is  possible  to  configure  a  service 
between a C37.94 and an E1 or T1 port. In this way, it is possible to transport a C37.94 link 
further on over an SDH cloud or network, see §2.2.7 for some examples.

E1 Framing 

E1 is a 2.048 Mbps bi-directional (full duplex) link through which the data is transported in a 
digital way in frames. One frame consists of 32 time slots (Figure 6). Timeslot 0 is used for 
framing and synchronization, and time slot 16 for signaling. The bandwidth of one time slot 
is  64  kbps  (=8  bits/125  µs).  One  frame  thus  consists  of  32*8  =  256  bits  and  lasts  
125 µs. Typically 16 frames are packed together in one multiframe.
