This system is evolving to STM16 / OC48 and can work in SDH or SONET mode depending on the software selection and choice of tributary cards.

This modular high density system can be configured with two aggregate rings STM1-4/OC3/12, up to 3 sub-rings STM1/OC12 SNCP/UPSR, or 6 STM1/OC12 MSP (1+1) or 1 STM4/OC12 MSP (1+1). Full cross-connect at VC11, VC12, VC3 to VC4 is provided. It is a true SDH/SONET HUB for the transport and distribution of PDH E1/T1/E3/DS3 links and Ethernet/Gigabit Ethernet LAN with QoS and high speed protection.

The HX9400R-6U tributary cards include:

252 x E1 or T1,
12 xDS3 or E3
32 x10/100BaseT or 6 x1000BaseT
6 x STM1/OC3 with MSP (1+1)
3 x STM1/OC3 SNCP sub-ring,
1 x STM4/OC12 with MSP (1+1
32 x 4 RS232 asynchronous
or the mix of this card with 8 slots
The redundant central cards of the HX9400R system integrate the CPU, the cross-connect and the independent support of two SFP modules per card. The 4 SFP on the two CC4 (CPU) cards can be equipped with STM4/OC12 or STM1/OC3 modules to provide the following aggregate configurations:

In SDH

2 Ring STM1/4 SNCP or
1 Ring STM1/4 SNCP and MSP (1+1) with 4 fiber or
2 Bus STM1/4 MSP (1+1) or
1 Ring STM1/4 SNCP and 1 Bus MSP (1+1)
