CXR SDH 

          The HX9416-RA is the last largest configuration of HX9400R series of the ADM/TM SDH multiplexer range from CXR. This configuration with two CC16 CPU/aggregate provides a concentration of traffic over the two STM16 (2,488Gbps) SNCP rings, plus up to 8 STM1 or 2 STM4 sub-rings or STM16 MSP in a single node. It supports the full cross-connect of all VC12, VC3 and VC4 of all interfaces.

This new generation equipment, based on SDH+ technology, is designed to have full non blocking add & drop capabilities of the following tributaries:
• 252 x E1/T1 protected (1+1) or 504 unprotected
• 12 x DS3/E3 protected (1+1) 
• 64 x 10/100M Ethernet 
• 8 Gigabit Ethernet or 
• 32 Gigabit Ethernet with HX9400R-CB-
• 8 x STM1 with MSP (1+1) or 
• 8 x STM1 SNCP Ring 
• 4 x STM4 with MSP (1+1) or 
• 2 x STM4 SNCP Ring 
• 1 x STM16 with MSP (1+1) Or a combination of all The modular SDH-ADM node HX9416-RA supports 2 STM16 per card CC16 and 4 STM16 payload per chassis with 2 CC16 card. The selection of the STM1-4-16 is operated by software selection and SFP module exchange .
