8.7 Adding the z14 ZR1 server to a CTN This section describes the procedure that is used to add a z14 ZR1 CPC to a CTN. As shown  in Figure 8-53, we add a z14 ZR1 (MUSCA) to the CTN with the ID CTLSOMRS.  At the beginning of the process, the MUSCA CPC is connected by using coupling links to a  LEPUS and CETUS, but it is not assigned to any CTN. When added to the CTN, CETUS  becomes a Stratum 2 server.  Next, we describe how to assign the Arbiter role to MUSCA.
