Note: Because the bandwidth of upstream and downstream PON ports is fixed, the number of
enterprises connected to an OLT is limited when the enterprises require symmetric bandwidth.
When an enterprise requires 100 Mbit/s symmetric bandwidth and uses an 8-channel PON board:
1. The number of enterprises or branches connected to a PON port should not exceed eight.
2. The number of enterprises or branches connected to a PON board should not exceed 64.
3. The number of enterprises connected to an OLT cannot exceed 200 (20G/100M) if the
upstream bandwidth is 2 x 10GE. (The number of enterprises connected to an OLT is mainly
restricted by the upstream bandwidth.)

Figure 12-14 shows the configuration procedure for Layer 2 interoperation between branches
of an enterprise.
