The STSX ACIC's provide 8 x STS-12 and 4 x STS-12/48 circuits. Adding
these values together gives you the maximum number of STS-1 circuits that
you can provision on a single XC or XC-VT. This maximum value is 288

The VTX ACIC provides 24 x STS-1 circuits. Each STS-1 circuit can carry a
maximum of 28 VT1.5's.  Adding these values together gives you the
maximum number of VT1.5 circuits that you can provision on a single XC-VT.
This maximum value is 336

A single VT1.5 has been mapped onto an STS-1 circuit. Although it possible
to groom a maximum of 28 VT1.5's onto a single STS-1here we are only
using a single VT1.5. This will burn 1 STS-1 circuit leaving only 23 free
STS-1 circuits left. The maximum number of STS-1 circuits between the
STSX ASIC's and the VTX ASIC is 24

24 STS-1 x 28 VT1.5 = 336 VT1.5

The STSX ACIC's provide 8 x STS-12 and 4 x STS-12/48 circuits. Adding
these values together gives you the maximum number of STS-1 circuits that
you can provision on a single XC or XC-VT. This maximum value is 288

The VTX ACIC provides 24 x STS-1 circuits. Each STS-1 circuit can carry a
maximum of 28 VT1.5's.  Adding these values together gives you the
maximum number of VT1.5 circuits that you can provision on a single XC-VT.
This maximum value is 336

The single VT1.5 is now mapped onto a second STS-1 circuit. Although it
possible to groom a maximum of 28 VT1.5's onto a single STS-1here we
are only using a single VT1.5. This will burn a  second STS-1 circuit leaving
only 22 free STS-1 circuits left. The maximum number of STS-1 circuits
between the STSX ASIC's and the VTX ASIC is 24

Each STS-1 can carry up to 28 VT1.5's. In this example
we have groomed all of the 28 VT1.5's onto the STS-1
circuit connected to port 1 in order  to use 100% of the
available bandwidth. We have made maximum use of this
STS-1 circuit between the VTX and STSX ASIC

Ciircuit type can be STS, VT or VT tunnel. Although an STS-1
should be groomed to carry 28 VT1.5's we are deliberately
only going  to assign a single VT1.5 to each STS-1 in order to
show the 24 STS-1 limitation on the VTX ASIC for VT circuits

Uncheck this  box so that  you have to provision the circuit
spans and set the circuit path manually

The XC-VT card enables you to additionally go beneath the STS-1 level and provides VT1.5 cross-
connect capability.

The VTX ASIC provides 24 STS-1 circuits onto each of which up to 28 VT1.5's can be groomed.
This provides a bandwidth of (24 x 28) or 672 VT1.5's. However each VT1.5 connection requires
two circuits so the simultaneous number of VT1.5 connections  that can pass through the XC-
VT card is 336

A VT1.5 on any VTX input port can be mapped to any VTX output port

The XC-VT card is designed to be non blocking, which means that all 336 VT1.5 connections  can
simultaneously be used to their maximim capacity. Even if an STS-1 is only partially filled, every
VT 1.5 in the STS-1 is terminated on the VTX. When every VT 1.5 in an STS is used, and all of the
VTX ASIC's STS-1 ports are consumed,  there is enough capacity on the VTX to switch every VT
1.5 in every terminated STS. Therefore, one counts STS-1 terminations on the VTX instead of VT
1.5 terminations

The VT-XC card provides the equivalent of a bidirectional STS-12 for VT1.5 traffic

The number of STS-1 ports on the VTX ASIC is 24. When all 24 ports are used, no additional VT
1.5's can have access to the VTX matrix

The XC card has 12 input ports and 12 output
ports. Four of the input and  output ports operate at
either STS-12 or STS-48 rates. The remaining
eight input and output ports operate at the STS-12
rate. This provides a maximum bandwidth of (8 x
12 + 4 x 48) or 288 STS-1 circuits. However each
STS-1 connection requires two circuits (source and
destination) so the effective simultaneous number
of STS-1 connections that   can pass through the
XC card is 144

* An STS-1 on any input port can be mapped to any output port

* The STS-1switches traffic at the STS-1 level. Traffic switched goes directly between the STSX ASIC's

* The XC card is designed to be non blocking, which means that all 144 STS-1 connections can simultaneously be used to their maximim capacity

* The maximum number of simultaneous STS-1 circuits that can pass through the XC card is 144

* All 144 STS-1 circuits on the XC card can be used to their maximum capacity

* The maximum number of VT1.5 connections that can pass through the XC-VT  card is 336

* All 336 VT1.5 connections can simultaneously be used to their maximim capacity

* When calculating capacity in the VTX ASIC count the number of STS-1 circuits that terminate on the VTX ASIC

* The maximum number of STS-1 ports on the VTX ASIC is 24. When all 24 ports are used , no additional VT 1.5's can be created

* The XC card performs STS to STS switching only. There is no switching at the VT level

* The XC-VT card additionally allows you to map VT1.5's from one STS to multiple STS's, or perform TSI on the VT 1.5s

   However, it does not convert between the two different mappings
3 Each of the 4 STS streams can be configured in multiples of STS-1s or STS-3c
4 The STS stream can be configured in multiples of STS-1s, STS-3cs, STS-6cs or STS-12c

you see this error message you need
verify the VT1.5's have been correctly
