SBI bus. This is selected when the SYSOPT[2:0] bits in the Global Configuration
register are set to “SBI Interface with CAS or CCS H-MVIP Interface” and the
ICCSSEL bit in the T1/E1 Ingress Serial Interface Mode Select register is set to
0.
A separate H-MVIP interface consisting of a single signal is used to time division
multiplex the common channel signaling (CCS) for all T1s and E1s and
additionally the V5 channels in E1 mode. The CCS H-MVIP interface, CCSID, is
not multiplexed with any other pins. CCSID can be used in parallel with the Clock
Slave:H-MVIP mode when SYSOPT[2:0] is set to “H-MVIP Interface” and the
ICCSSEL bit in the T1/E1 Ingress Serial Interface Mode Select register is set to
1, a Clock Slave serial interface when SYSOPT[2:0] is set to “Serial Clock and
Data Interface with CCS H-MVIP Interface”, or the SBI Add bus when
SYSOPT[2:0] is set to “SBI Interface with CAS or CCS H-MVIP Interface” and
the ICCSSEL bit is set to 1.
When accessing the CAS or CCS signaling via the H-MVIP interface in parallel
with serial clock and data or SBI interfaces a receive signaling elastic store is
used to adapt any timing differences between the data interface and the CAS or
CCS H-MVIP interface.
Figure 26: Clock Slave: Serial Data and H-MVIP CCS
When Clock Slave: H-MVIP mode is enabled, payload data may be extracted
throught the ingress serial interface, while common channel signaling is
extracted in parallel through the H-MVIP interface.
The H-MVIP ingress interface multiplexes common channel signalling from up to
28 T1s or 21 E1s. The H-MVIP interfaces use common clocks, CMV8MCLK and
CMVFPC, and frame pulse, CMVFPB, for synchronization. Common channel
signaling over H-MVIP uses a Clock Slave serial interface, selected when
